#2 Decca Records A&R exec tells Fab Four, “No, thanks”
Dick Rowe was not the only record-label executive who passed on the Beatles in the early ’60s, but he was the only one who brushed off their manager, Brian Epstein, with the astute prediction that: “Groups with guitars are on their way out.” Epstein begged Rowe to reconsider, so Rowe hopped a train to Liverpool to check out the band live. When he arrived at the Cavern, he found a mob of kids trying to force their way into the club in the pouring rain. Annoyed, he smoked a cigarette, went home and signed Brian Poole and the Tremeloes instead.
