I have no idea where this was taken. Carl sent it to me of the boys sometime around 1974, I am guessing. They were performing as a 5 piece band at that time.
And for this number they had John Carstensen on guitar, Jon Ludtke on guitar, Denny Walton switching from guitar to bass, Kim Ludtke on drums and Steve Elliott switching from bass to pedal steel guitar.
I tried to recover some of the photo using an editor, but the picture is faded and very dark. It was the best I could do with my limited abilities.
