HW: 1975 Feb 16, Roundhouse tracklist?

[Carl Edlund Anderson]

I recently downloaded what claims to be a copy of HW at the  
Roundhouse on 16 Feb 1975, but I'm having difficulty figuring out  
what some of the instrumentals in the tracklist are (whether they're  
actual known named instrumentals for which the ropey sound is  
defeating my ears, or whether they're just some unknown stuff!).   
Anyone know the details?

Cheers,
Carl
