This live performance from 1973 with Derringer & Winter, plus Dan Hartman on bass & Chuck Ruff on drums is good, too. Video quality is a bit rough, and there is a pause in the middle, but the guys wailing on vocals & their instruments is extraordinary:

That is a great video, one of my favorites. Chuck Ruff on drums is hilarious, they are all having a blast.
