1954, The Blue Moon Boys, featuring Elvis Presley, Scotty Moore, and Bill Black, made their live debut at the grand opening of a drug store in Memphis, TN. The band’s name was taken from the song ‘Blue Moon of Kentucky’ which they had recorded a few weeks prior.
1968, ‘In-A-Gadda-Da-Vida‘, by Iron Butterfly entered the US album charts. The 17 minute title track was supposed to be called ‘In the Garden of Eden’ but lead singer Doug Ingle was so drunk when he recited the lyrics to the band that it was interpreted as In A Gadda Da Vida. The song is considered an early influence on metal.
1975, Bruce Springsteen and the E Street Band played the opening night on their Born to Run tour in Providence, Rhode Island only hours after finishing recordings for the album. The show was also the live tour debut of Steve Van Zandt (Miami Steve, Little Steven).
