I heard rumor the Mike Howe was no longer in the "biz" and wasn't really in the shape to do it anymore. A shame if it was true I really dug the era of Metal Church. But this came from a band that was looking for him as a possible singer.
As for Metal Church iit looks like is did end from lack of interest, but who knows. But a year or two ago there was talk of a Metal Church band touring that would have Monroe but no original members in it, basically a cover band still they would bill it has MC. Personally I think ideas like that are stupid.
