Stephen Couch of the Betweeners and Fattlabb working out to an Aebersold play-along of Sonny Rollins tunes while wating on a tardy student. The slide guitar segment gets started at about the 3:00 mark. The first bit is straight guitar over “St.Thomas”, the slide guitar section is just a blues called “Blue Seven”. The melody is not stated on either tune since this was just practicing improv over the chnges. You even to get to hear Stephen take a second to tune his high “E” down to “D” to get into his slide tuning.
