Ed Cassidy (far left in the above picture), founding member and drummer for the 60s band Spirit, died yesterday at the age of 89.
I've long held a belief that some of the best rock musicians are forged in the fires of jazz, and Cassidy was no exception. According to his Wikipedia entry, the man once played 282 consecutive one-nighters in 17 states in the late 40's. Just let that sink in for a second.
Here's their biggest hit single, "I Got a Line on You" from their 1968 release The Family That Plays Together.
