The song remains the same, as Led Zeppelin once observed. But Zeppelin fans can visit the band's music anew thanks to a film of the rock titans' last show together in 2007.

That was the band's first full show in 27 years. Singer Robert Plant, guitarist Jimmy Page and bassist John Paul Jones got together again Friday to promote the film -- but that may be as close as fans will get to a new reunion.

At a news conference, the members flatly declined to answer when asked if they were tempted to perform together as Led Zeppelin.

Plant said that even lining up onstage to answer questions -- "like a bunch of soccer managers being interviewed after a match" -- was not his idea of fun.

The band members have moved on, with Plant in particular finding success in other genres. He has played with musicians from Mali and won a Grammy in 2009 for his rootsy collaborations with bluegrass musician Alison Krauss.
