"Boulder, CO, Fox Theatre. Giant Panda at 9. JBB at 10. TK at 11:30. Bring your dancing attire, dr."

In 1966, Otis Redding had emerged not only as the star of Stax Records but as one of nation’s most influential soul singers. With his version of “Satisfaction” climbing the charts in April 1966, Redding arrived in Los Angeles to play both the Hollywood Bowl (as part of a KHJ-AM listener appreciation concert that also featured Donovan, Sonny & Cher and the Mamas & the Papas) and a four-nighter at the legendary Whisky A Go Go on the Sunset Strip.
