Here's your daily look at 'Today in Rock History' featuring: Glen Matlock from the Sex Pistols is 63. Alex Lifeson from Rush is 66. Pee-Wee Herman, a.k.a. Paul Reubens, is 67. Sergeant Slaughter is 71. Today in 1965, The Beatles hung out with Elvis Presley for three hours at Elvis' Beverly Hills mansion. Elvis says he doesn't remember the meeting--that's gotta be like four guys riding in a pickup truck, and then asking the pick-up if it remembers the ride... AND today in 1990, the great Stevie Ray Vaughan and members of Eric Clapton's entourage died in a helicopter crash in East Troy, Wisconsin leaving Alpine Valley. RIP
