Here is the line-up card...
1980-On this album Iggys band is: Ivan Kral Klaus Kruger Steve New Barry Andrews and Glen Matlock (Sex Pistols). Song Writing Credits: Glen Matlock #2 Glen Matlock/Iggy Pop #6,8,9 David Bowie/Iggy Pop #4 with chorus sung by Bowie & Simple Minds That's the line-up, most folks don't know about the Bowie appearance. The song wasn't really promoted as far as I know. The vinyl was labeled as "This Side" and "That Side" (1 & 2 respectively). A sometimes moody piece, but 1980 was like that (for those that were there). I'm not familiar with the last two tracks, I assume they are outtakes. Knocking 'em Down is a good track to play at high volume. A very solid solo effort by Iggy and band.
