I've got quite a few of those. But I don't think so - basically, that other material is good (or you wouldn't have two or more copies, would you?).
I have quite a lot of LPs that I keep for only one side, because the other side is, to use a technical term, shitty. But if we're talkking about items we keep for only one track, I can't think of any of those LPs that qualify.
However, I've got a few that I only bought because so and so played on one or two tracks (sometimes not even terribly audibly) and I think these qualify, so I'll list them.
Bruce Fisher - Red hot - Mercury (Charles Earland is on two tracks of this, but it's rubbish all the way through from what I can remember)
Roy Nathanson - Fire at Keaton's Bar & Grill - 6 Degrees (Earland is on a couple of these tracks, too)
Saka Acquaye - Gold Coast Saturday night - Elektra (Earland on tenor sax)
Case - Personal conversation - Def Soul (Mel Sparks is on one track)
Bobbi Humphrey - City beat - Malaco Jazz (Gloria Coleman on one track)
Various Artists - Kairo: songs of the Gambia - Kerewan Sounds (one track is by a friend, Sambou Susso, who is a great singer)
MG
