Well weather or not Bush could bull off the older songs is up to ones own opinion. Some people think he sounded bad doing it - others, like me, thought he sounded better then Joey. I gots mad respects for most of you people, and I am not one to tell someone there opinion is wrong. I just can't see Joey pulling off Bush songs. I have heard a lot of "screamers" pull off power-metal style shit. But it seems when a power metal singer tries to pull off a screaming song, it just does not fit as well. Perfect example - Dream Theater. I LOVE DT with all my heart and soul. But when James sings Metallica songs, it does not sound right. He sings them better then James Hetfield (hahaha) but it just does not fit.
