Theme-Jam-Theme songs

List the mostly-psychedelic-era songs that consist of a theme, then a jam of an indeterminate amount of time, then a resurgence of that theme.

Pink Floyd - Interstellar Overdrive
Led Zeppelin - Mody Dick
Rush - YYZ

Pink Floyd - Echoes (go figure)
Light My Fire

“Blinded by the Light” as performed by Manfred Mann?

Sonic Youth’s “Silver Rocket” isn’t remotely psychedelic, but it fits the general pattern.
