I was a 15 year old and had just moved to Hanover, NH with my family in 1967. My first walk into town was on a Friday night, and I went into the MUB, Dartmouth College's student union building. There was some music coming out of Spaulding Auditorium (one of the most accoustically perfect rooms in the country) and I wandered up to the door. Out burst a couple who were ranting about how awful the band was and they threw their tickets into a trashcan. I grabbed a ticket and went in and sat down to see the most influential concert of my life. It was the Butterfield Blues Band touring in support of 'In My Own Dream'. Bugsy Maugh doing I got my Mojo, Gene Dinwiddy with his throat in Gillespyism playing his heart out, and Paul cranking his harp. It totally blew me away, and I was changed forever.
I have over 350 concert tickets at home now, and I still consider this show in my top 3 of all time. It was awesome.
