Any favorites? Mine include "Suzie Q", "Roundabout", "Child in Time", "Twilight Zone", "Strange Kind of Woman (live)", "Blinded by the Light", "Miss You (8 minute version)", and "Slow Ride (8 minute version)", as well as several tracks from Rush and Pink Floyd.
Also forgot "I Heard it Through the Grapevine" by Creedence Clearwater Revival, which clocks in at over 11:00- CCR seems to be really great at extending their jams when it is do-able.
