A Led Zeppelin Concert Film...
Peter Grant contacts director Joe Massot and makes arrangements to film the band in concert. Massot had approached the band earlier in the year and pitched his idea about a film project on the group but was initially turned down.
He would meet with Peter Grant and road manager Richard Cole days later in Boston to make the arrangements. Some offstage filming and test concert footage began in Pittsburgh on July 24th. Three shows at New York's Madison Square Garden are filmed and used for The Song Remains Same movie released in 1976.
