I had a hankering for Yellow Pearl the other day,
and went looking for it on iTunes -
you can get the "original version" (which I imagine is the one from Solo in Soho) and one labelled "first remix" (which sounds more Top of the Pops).

I love on the original when Midge does this wee backing vocal that goes "We must fight Back!-ack!-ack!-back...!"

PS hello Gwilym.
