Roger Daltrey explores the turbulent relationship between Buddy Holly and his manager and producer, Norman Petty. Niki Sullivan and JI Allison, guitarist and drummer with The Crickets, and Buddy's widow Maria Elena reveal that all was not well between the pair, and the tensions led to a split. Roger hears how Petty made a series of unusual business decisions on behalf of the band, and accrued writing credits - and consequently royalty payments - to himself which are still causing financial difficulties some 50 years on.
