Elton John played the Minneapolis Auditorium on August 31, 1971.  Facebook fact:  his sidemen included the former rhythm section of the Spencer Davis Group.  Ad below from the Insider; photo courtesy David Tanner.  That year, DJ Barry McKinna was the first person to play a song not on a record in the Twin Cities – a tape cartridge of Elton John’s “Crocodile Rock.”  Also on the bill was Dan Hicks and His Hot Licks.
