But it's not the studio cut
that had Steve Jones play the riff in a more monolithic fashion (Andy McCoy has more of a Keith Richards groove). The bass is different too (as is Iggy's vocal) and it's quite a bit faster. So if it is indeed pre-recorded, then this line-up must have done it und lip-synched it very well.
I'm no Iggy or Steve Jones biographer, but my understanding is that while Steve Jones played the guitar on Iggy's 1988 Instinct album (unjustly derided as an "LA Metal album" at the time) and did the odd TV appearance
(that's him with the Les Paul on the right, long curly hair and all),
he didn't do the ensuing tour where the little Finn took his place.
