[HAM] This BLINDFOLD TEST is Not a Test It's a Groove

[OF]

This one's just for total ass-rockin' fun. Jazz? I doubt it. Many of you 
will recognize him. Some of you may have heard this tape, but that would 
have been years ago. It's live, I recorded it, it's HIM (WHO?), and it's 
ripped-woofer-time. "Recalibrate?!" you might have heard him say...."Man, I 
just play, I'm not worryin' about stuff like that!" ("Pssst.......sshhh! 
Scott? First would you just check to make sure there's no horsehair pillows 
in that 147 over there? If there is, kin I sit on one?"

For extra credit, what's that chord he's playing as a fanfare for the sax 
soloist at 1:57  and 2:45?
You can spell out the notes instead of naming the chord. If you figure it 
out, your prize is having the pleasure of having learned that as something 
cool to do in a 'C' jam.
