A Pink Floyd comeback would be the greatest gig in the sky, according to the findings of a new Europe-wide poll.

When asked "Which band would you most like to see re-form," more than 26% of respondents to the census, published today by digital music firm Music Choice, said a reunion of the prog-rock legends was top of their wish-list. Swedish pop giants Abba was the next best thing, gathering support for a comeback from more than 19% of interviewees. Rock titans Guns N' Roses were third on the list with 15.73%, followed by The Jam, Talking Heads, The Fugees, Van Halen, Wham!, Spandau Ballet and Boyzone.

Music Choice undertook the study in the wake of unrivalled consumer interest for the one-off Led Zeppelin performance in London on Nov. 26. Organizers of the Ahmet Ertegun tribute concert have claimed more than 20 million people registered for the available 18,000 tickets in just a matter of hours.

"When Zeppelin announced their gig, we wanted to see just who else would be a smash hit live in Europe, so we turned to music fans to find out," says
Andrew Jeffries, worldwide director of music and programming for Music Choice, in a statement.

On the flip side, more than 22% of interviewees declared the Spice Girls the band they "would most like to see split up." The girl group, who will hit the road for a world tour beginning Dec. 2 in Vancouver, Canada, were immediately followed on the list by boyband Westlife and reality-TV created pop outfit Girls Aloud.

"Although we knew Pink Floyd might be a contender, we never dreamed they'd be the top choice, and we were amazed that so many fans wanted to say "goodbye" to Posh and Co," adds Jeffries. "It's fascinating to see their response and we're looking forward to analysing the full results of the music census shortly. Anything could happen."

Full results of the survey, which was based on a sample of 5,000 music fans, will be published at www.musiccensus.com after the census closes Sept. 30.

Music Choice says the study will illustrate Europeans' downloading habits, favorite tunes for different occasions, musical role models, and views on the future of CDs, downloads and ringtones.
