ELO, Deep Purple 11-Dec-1974. Dio was scheduled to open the show and cancelled at the last minute. $6.50 got me a dozen rows from the stage. Eldorado and Burn were the tour's featured albums.
A cello blew up during ELO's show. Ritchie Blackmore came back with an open, mostly full, dripping bottle of whiskey to use as a slide during the encores. The first of many awesome shows.
Relax, have an Oso Lupulin Maximus Imperial IPA and listen to some Legendary Blues Band...
