The Kingdom Come listed is, I think, the Arthur Brown's Kingdom Come (as in the former Crazy World Of Arthur Brown fella) - not the 80's Zeppelin clones just in case you were wondering why they were there.
Apologies if I got that wrong though.
Anyhoo, I gotta say it seems a little churlish to pick at individual choices made by people who are simply putting their choices forward for this list in goodwill hmm?
