… actually, it was "The Day the Music Died." On this date in 1979, a commemorative concert is held at the Surf Ballroom in Clear Lake, Iowa, exactly 20 years after the final show played by Buddy Holly, Ritchie Valens and the Big Bopper. Del Shannon and the Drifters are among the performers. Here's local Mpls faves the Whitesidewalls, who had performed at the 1979 concert, rippin' it up in 2009 with "Peggy Sue."
