You know I wonder why Ace wasn't there? He played on the original studio version and played this song live with the band often. Ace was with them again in 1992. 

There is Ace right at the beginning!! 

Jack Pearson with Los Lobos...Don't Keep Me Wondering.

Looks like Duane is playing Derek's SG here. As far as I know Derek plays a custom shop replica of that guitar today. 

Jack Pearson is over in a room all by himself when he plays slide guitar.  Some of his licks are so off the wall I sometimes wonder if most real good slide players would find them appropriate.

This has Don't Keep Me Wondering on it. I didn't have this show in my stash. Most of it is a 1971 radio show from a Chicago radio station. It may be a good audience tape, not sure.
