My friend Mark Greenberg brought the legendary Staples Singers lead vocalist Mavis Staples into the studio last week to record a song for a commercial. Mavis was amazing. She hasn't lost a thing since she cut "I'll Take You There" at Muscle Shoals in the early seventies. Yvonne Staples hung out with us as well. My favorite part of the session is when Mavis took a break and told all of us young cats several stories of all the famous people she's worked with over the years: Prince, Martin Luther King, Jackson Brown, Aretha, Curtis Mayfield and many others.
