There's a live stream tonight from L'Olympia of a special event with Led Zeppelin guitarist Jimmy Page.
The event is to mark the release of the special editions of Led Zeppelin's I, II and III albums, which come out early next month.
It's being held at L'Olympia because the new special edition of Led Zeppelin I features a live recording of the legendary band at the Paris venue, recorded on October 10 1969.
The gig was recorded by French radio and broadcast on the Musicorama programme in November 2 1969. The tape was rediscovered in 2007 and re-broadcast later that year.
Bootleg versions of the set have appeared in the past, incomplete and of a lower quality, but the new version has been mastered by Jimmy Page and features the entire nine-song set.
The 1969 Europe Autumn tour was a short one for Led Zeppelin, just five dates long with concerts in Scheveningen, Rotterdam and Amsterdan preceding the Paris show, and one night in London at the Lyceum Ballroom on October 12 following it.
Later that month they would again be off to north America, starting at Carnegie Hall in New York on October 17, where they would continue to establish their reputation as one of the biggest rock bands the word's ever seen.
