I used to know (via a friend) a guy who later joined Paul Young in the Q-Tips. "Toast" was Streetband's joke track, which came about when the band had some spare studio time and were just mucking about.
Saw Streetband several times. it was funny to see how many home counties yuppies would rock up to the gig expecting a convivial evening's amusement (like Toast), and then being dismayed to discover the band's regular output was actually hard blues......
