At the 3min mark of this '75 Capitol Theater gig you can see Dawson strumin' a cool lookin' Alembic.
'Wonder where that guitar is nowadays???
Buddy Cage also has two Pedal Steels setup (see as camera mags out around 55sec mark)... I think he was making the transition form a Double Neck 10 string Emmons, to a Double Neck 12-string Hilt at this time.
Also, Skip Battin on Bass.

Another one from that night (Nelson is playing a Strat! [see 2min:35sec mark]):
