Sure, Sammy Hagar likes to party down, chug a load of tequila and not drive 55, but when you get right down to it, even the red rocker has a heart. In January of this year, he organized and played a benefit with all proceeds from the $150–$250 ticket going to a three-year-old recovering from a kidney transplant, and this Saturday, he premieres his new movie, Go There Once, Be There Twice, and turns in an acoustic set with his band the Wabos to benefit Homeward Bound dog rescue and Ritter Center homeless services. See him in a tiny venue on Saturday, Dec. 11, at 142 Throckmorton Theatre, 142 Throckmorton Ave., Mill Valley. 7pm. $100. 415.383.9600.
