Track 3
What's the Buzz (feat. Ian Gillan & Yvonne Elliman) / Strange Thing Mystifying (feat. Murray Head & Ian Gillan)
Track 7
Simon Zealotes (feat. John Gustafson) / Poor Jerusalem (feat. Ian Gillan)

With both tracks, AR is currently done at the track level. Using AR on 7 for instance would imply that both John Gustafson and Ian Gillian performed on both Simon Zealotes and Poor Jerusalem which isn't accurate at all.
