I did a bit of digging around this one not too long ago, many of the tracks (or at least something by those same artists) are to be found around the web.
Of the bands i've heard...
Alecstar were a Pomp/Hard Rock band who put out a couple of albums.
Mr. Edd : oddball ska/reggae with a new wave edge.
Moss Back Mule Band played Country, as did the The Dust Devil Band.
The Works played mainstream rock with prominent piano.
New York Flyers played Hard Rock, verging sometimes on Metal onstage, but more restrained on vinyl.
Joe Whiting and the Bandit Band were kinda Springsteen like rock
Holmes And Mancini were a folk/soft rock duo.
Todd Hobin Band were AOR.
That leaves 3 acts.
We know that the Justice McBride Band were Southern Rockers & Discogs has Kentucky classified as a 'Southern Rock' band too, with a self-titled 1982 LP to their name.
Who knows what The Netherlands Band sounded like, (a bit flat maybe?

), but frankly the name isn't very promising.
So for Corroseum purposes, i guess the question is, are you prepared to take a punt on it for the non-LP Justice McBride track, with Kentucky being
potentially interesting, and in hope that the Alecstar & New York Flyers songs are up your alley?
If you can find it for the price of an EP, i'd say go for it.
Hope this helps.

I cannot, I shall not, I will not obey.
