The oldest and greatest rock band in the world - meet The Zimmers and their amazing cover of The Who's "My Generation". Lead singer Alf is 90 - it's quite something when he sings "I hope I die before I get old". And he's not the oldest - there are 99 and 100-year-olds in the band! It was recorded in the legendary Beatles studio 2 at Abbey Road. Look out for the single being released from May 21 - with proceeds going to a good cause.
