Jem Aswad Senior Music Editor What a long, strange trip the long-lost Creedence Clearwater Revival Royal Albert Hall concert album and film has taken in the half century since it happened. The show and the on-the-road footage were recorded by the BBC during the group’s first European tour in April of 1970, but never broadcast. The recording presumably got hung up in the notorious legal battles between the group and its original label, Fantasy Records, although footage from the concert popped up at various times over the decades (even in a TV commercial for a budget Creedence greatest-hits album in the ‘80s). Even more confusingly, Fantasy released a very similar live album titled “The Royal Albert Hall Concert” before realizing that the tapes had been mistakenly labeled and the album was actually recorded ten weeks earlier and 5,000 miles away at the band’s triumphant Oakland Coliseum homecoming concert (the album was quickly retitled “The Concert”).
