Led Zeppelin are reportedly about to reunite for a one-off memorial concert.

If true, it would mark the third time that the '70s legends have played since disbanding.

After the death of drummer John Bonham in 1980, founding members Robert Plant, Jimmy Page, and John Paul Jones regrouped for Live Aid in 1985 (with Phil Collins) and for Atlantic Records' 40th Anniversary concert (with Bonham's son Jason).

It is now suggested that the latter formation will play a special concert in memory of Atlantic Records founder Ahmet Ertegun in London.

A source said: "Page, Plant, and Jones spoke and agreed to do the memorial concert. They are waiting for a definite date.

"And no one can quite believe it, but during discussions about the concert they all gave the green light to a tour if it all does well and they don't all fall out.

"It has been hoped for and denied for years. But this is the closest they have ever come to a reunion tour. The feeling is that this is going to happen next year."

Ertegun died in December 2006, following a fall at a Rolling Stones concert. The likes of Eric Clapton, Neil Young, Stevie Nicks, and Crosby, Stills & Nash all played his New York memorial in April of this year.
