Flash and the Pan: C or D, S/D?

Are any of these Vanda and Young songs from the early 70s worth tracking down?

Paintbox "Get Ready For Love" (1970)
Tramp "Vietnam Rose" (1970
Eddie Avana "Children" (1970)
Moondance "Lazy River" (1970, A&M Records)
Grapefruit "Sha-Sha" (1971, Deram Records)
Haffy's Whiskey Sour "Shot in the Head" (1971, Deram)
Band of Hope "Working Class People" (1972, unreleased)
Marcus Hook Roll Band "Natural Man"
Marcus Hook Roll Band "Louisiana Lady"
Marcus Hook Roll Band "Can't Stand the Heat"

Man, I had never to my knowledge really heard of these guys. What a weird musical footnote.

Midnight Man is one of my all time favourite songs
