i know they didn't sell many records, but it hadn't actually occurred to me that one could view The Frank & Walters in that way! For the record, i wasn't really a fan of the other bands you mentioned. I don't see The Franks sounding remotely like Carter USM either.
Edit* And i don't see that billing comes into it either - that it matters where in the billing a band is in terms of the quality and enjoyment of their music
