Robert Plant has ruled himself out of further collaborations with the band
Led Zeppelin should not hit the road for a major tour with a new singer, promoter Harvey Goldsmith has said.
Members of the legendary rock group have auditioned vocalists to take the place of frontman Robert Plant.
"I certainly don't think they should do a big tour because I can't see the point of it," Goldsmith said.
Goldsmith, who promoted the band in the 1970s and '80s, as well as their one-off reunion last year, added there may be "some opportunities" for a reunion.
He added that, should guitarist Jimmy Page, bassist John Paul Jones and drummer Jason Bonham recruit a new singer, they would be likely to tour under a different name.
"I doubt it will be called Led Zeppelin," Goldsmith told BBC News.
But he said: "I just think it's a lot of talk, I think it's wishful thinking. Whether they all come together and do something in the future, they may.
"I think some of the band really want to go out and do it and other parts of the band need to understand why they're doing it, and if there's no compelling reason to do it, then they shouldn't do it.
"I think that there is an opportunity for them to go out and present themselves. I don't think a long rambling tour is the answer as Led Zeppelin."
"It's a question of whether they want to do it, and you've got to want to do it," he went on.
"Otherwise it's done for the wrong reasons, and when things are done for the wrong reasons, they don't work."
Speaking at the MusExpo music conference in London, Goldsmith said he would "hopefully" be involved in any comeback.
Any potential gigs could be "cause related", he said, or "opportunities to view them in a different way".
The band, including Plant, performed at a tribute gig to late Atlantic Records boss Ahmet Ertegun at the O2 in London last December. That was their first show for 19 years.
'Trying out' singers
Last month, the singer said he would not be going on the road with the group. His former bandmates have now confirmed that a new singer is being sought.
Jones told BBC Radio Devon: "We are trying out a couple of singers.
"We want to do it. It's sounding great and we want to get on and get out there."
He said they did not want a replica of Plant. "It's got to be right," he said. "There's no point in just finding another Robert.
"You could get that out of a tribute band, but we don't want to be our own tribute band.
"There would be a record and a tour, but everyone has to be on board."
