The studio version is the B-side to "Panic". Besides the vinyl format, I think it exists on a CD single.
It's worth tracking down. The live version on "Rank" is better-- faster, louder, played with more urgency. The studio version is slower, a little funkier, and has some shimmering synths fluttering through the mix. It's not as good as "Oscillate Wildly", but better than "Money Changes Everything".
Had the original track been more guitar-laden, as it is on "Rank", then Morrissey probably made a mistake in not adding words. However, if the final studio version is even close to the one Morrissey heard, declining to favor the tune with his vocals was probably a good decision. Either way it wasn't a "surefire" number one, as Geoff Travis is said to have gushed.
