Inspired by Aswas' recent post, here's some info about Yes 2004-09 from Wikipedia (Yes (band)):
Since 2004, Yes has been on hiatus. In lieu of releasing new albums, they formed deals with Image Entertainment and other video firms to release past concert performances, music videos, and interviews on DVD. Howe, Squire, Wakeman and White had all expressed an interest in recording and touring, but Anderson had been firmly opposed because of personal health concerns. Thus, band members have pursued varied solo projects. White has formed a new group, White, featuring Downes. Their debut album, also called White, was released on April 18, 2006. In 2004, Squire joined a reformed version of The Syn, one of his pre-Yes groups from the 1960s.
Plans for a joint tour by White, The Syn, and Steve Howe, which would have included the Yes members (with singer Kevin Currie from White) performing songs from Drama, were canceled. White joined the band for a tour in 2006. On May 16, 2006, Squire announced that he had left The Syn. On the same day, the original members of Asia, including Howe and Downes, announced that they would be reuniting for a 25th anniversary tour, which commenced in September. Anderson and Wakeman toured together in October 2006, and the set list for most shows featured Yes material along with songs from both their solo careers, and at least one ABWH song. In 2006, Sherwood, Kaye and White — along with guitarist Jimmy Haun — formed Circa, a supergroup formally announced in March 2007. On July 30, 2007, the band self-released on Internet their debut album, Circa 2007. Their debut live performance was held on August 23, 2007, at The Coach House in San Juan Capistrano, at which time the band performed its entire debut album followed by an hour-long medley of Yes songs.
Anderson has also composed some new music with Trevor Rabin. How this music will reach the public has yet to be seen.
In the first half of 2008, Anderson toured North America, Howe toured with Asia, and White toured with Circa.
In honour of the band's 40th Anniversary, Yes had announced a 2008 world tour, entitled Close to the Edge and Back. However, the tour was cancelled on June 4 due to Anderson's health problems. Per the press release, "Yes frontman and founding member Jon Anderson was admitted to the hospital last month after suffering a severe asthma attack. He has now been diagnosed with acute respiratory failure and was told by doctors this weekend that he needs to rest and not work for a period of at least six months or suffer further health complications. Upon receiving this news the band has determined that their tour plans need to be put on hold." The tour had been planned to feature Anderson, Squire, Howe, and White, and to also include Oliver Wakeman sitting in on keyboards, in lieu of his father, Rick (who bowed out on the advice of his doctors).
Anderson said the band was preparing four new "lengthy, multi-movement compositions" for the tour which are "very, very different," however, after the weak sales of 2001's Magnification, Anderson has said that "putting together an album really isn't logical anymore" and no announcement has been made as to a release of recordings of this new material in any form.
A separate, North American tour entitled "In The Present" began on November 4, 2008 in Ontario, Canada, featuring Howe, Squire & White, along with Oliver Wakeman on keyboards, and Canadian Benoît David on vocals. David was singing in progressive rock band Mystery and in a Yes tribute band called Close to the Edge. The shows were billed as "Howe, Squire and White of Yes," although many reports and outlets simply referred to the band as "Yes". The tour saw the return of material from the Drama album (Tempus Fugit and Machine Messiah), Astral Traveler from the Time and a word album (not played live since 1971), as well as one new Chris Squire composition, Aliens (Are Only Us From the Future).
In the official press release, Squire stated, "This isn't an attempt to replace Jon Anderson, because as we all know, that would be impossible. With Benoît, we are bringing in a talented singer so that we can go out and honour the music of Yes for the fans who have waited for the past four years to see us perform." Squire also stated to the Associated Press that he is hopeful Anderson will be well enough to do shows in 2009. Initially, Anderson stated on his website that he was "disappointed" and "disrespected" by the move and lack of contact the other members have had with him since his illness. Later, this announcement was removed from his website, and Squire has since said that the tour has Anderson's "blessings".
On February 9, 2009, Squire was rushed to a hospital with an unspecified "medical emergency" that required a operation on his leg on February 11, 2009. He required at least a month to recuperate, which resulted in the postponement of the remainder of the scheduled "In the Present" shows, mostly in the Western USA. After this incident, Howe returned to work with Asia.
Squire, Rabin, and White re-united at a benefit reception on 18 April 2009 in Snoqualmie, Washington, playing the music of John Lennon.
The tour resumed in the summer of 2009, with the same "In the Present" band, now simply billed as "Yes". This tour featured Asia as an opening act, with Steve Howe playing with both bands. The 24-date schedule began in Indio, California on June 26, and ended in Bethlehem, Pennsylvania on August 2. Meanwhile, Jon Anderson is doing a European solo tour.
Yes announced a European tour scheduled in fall and winter 2009 (from Olomouc, Czech Republic on October 29 up to Gothenburg, Sweden on December 12).
Squire announced plans for a new album after their European tour wrapped up.
