The BBC reports that blues-rock singer Joe Cocker died today at age 70. I know this isn’t a music blog, but my first memory of Cocker is a TV memory. It’s when he was the musical guest on Saturday Night Live in 1976 and John Belushi, already well known for his exaggerated-but-affectionate Cocker impression, came out on stage for a duet of “Feelin’ Alright.”
