Private Investigations - Dire Straits
The Division Bell - Pink Floyd, classical and electric.
I was only joking - Rod Stewart, long riff with classical, mandolin and electric in succession.
Samba Party - Carlos Santana.
Sylvia - Focus
Mouldy Old Dough - Lt Pigeon, the honky tonk piano playing, I know it's not guitar playing but any instrument played well should get mentioned.
Good call, I love that as well.
When we play Baker Street everyone loves the sax bit, but there is a great guitar bit about 2/3rds of the way in and our guitarist nails it.
