Until The Division Bell, Ummagumma was the only Pink Floyd album to feature a female instrumentalist.On the UK version, the "reflection" has Gilmour in front once again. On the US album (with the airbrushed Gigi cover), in the smallest "reflection", with Wright in the foreground, instead of another "reflection" the cover of A Saucerful of Secrets appears. In each successive "reflection" in the upper-left corner, they move each band member forward one space, with the front-most member going to the back. They are seated in the order, from front-to-back, of Gilmour (in his bare feet), Waters, Mason and Wright. The album is the last to feature photos of the band members on the outer cover, though both Meddle and A Momentary Lapse Of Reason would feature members of the band inside the gatefolds.The rear cover (or cover of the Live Album) shows the band's equipment laid out on a runway at Biggin Hill Airfield. Inside the cover is a picture of David Gilmour in front of the Elfin Oak. On the original American album version, however, this was airbrushed to a plain white sleeve, apparently from copyright concerns (though the Gigi cover appears in US CD version's booklet). The British version has the album Gigi leaning against the wall above the 'Pink Floyd' letters. The cover of the original LP varies between the British, Canadian and American releases.Neither CD release includes the picture of Waters' first wife, which had appeared on the inner-gatefold sleeve of the original vinyl issue. A digitally remastered version was released in 1994 in the UK and 1995 in the US. In 1987, this was re-released on a two CD set.The album was certified Gold in the US in February, 1974 and Platinum in March, 1994. The album reached #5 on the UK charts and #74 on the US charts, the first time they broke the top 100 in the US.The other had four solo segments, a half-side of vinyl each by Gilmour, Wright, Mason, and Waters. The live disc was recorded at Mothers Club, Birmingham, on 4/27/69 and the following week at Manchester College of Commerce, on May 2.The title Ummagumma supposedly comes from British slang for sex, but the band has stated the word means nothing at all.Lindy Mason* (Mason's 1st wife) - Flute (uncredited).Nick Mason - drums, percussion, all instruments on " The Grand Vizier's Garden Party" (except flute)*.Richard Wright - keyboards, vocals, all instruments on " Sysyphus" (keyboards, drums, guitar and voices).David Gilmour - vocals, guitar, all instruments and vocals on " The Narrow Way" (guitars, vocals, keyboards, drums and bass guitar).Roger Waters - bass guitar, guitar and vocals on " Grantchester Meadows", tape effects on " Several Species Of Small Furry Animals Gathered Together In A Cave And Grooving With A Pict".The track was dropped at the last minute, most likely to maintain the sound fidelity of the record, but numerous bootlegs were given to friends of the band including John Peel The band also recorded a live version of " Interstellar Overdrive", intended for placement on the live album. Original track times are listed in brackets above.
