Your band ain't so bad. I think the singers work better in conjunction than they do with lead vocals (something very 'stagey' about the overall sound, do they have a background in musicals?), and if you're serious about taking on songs of that caliber then you might want to invest in a better guitarist (or maybe get 2 of them onboard to share the load).
Also - ditch the backing during the opera section. It sounds intimidating at first and will take a bit of work to be fully up to speed, but you'll have a better band at the end of it.
Cheers!
Far from excellent or awesome, but yes, it's one of the better covers. Does the black guy sing in musicals? He sounds like a musical singer. And I miss the fun. That's the reason why I can't watch most cover bands - they concentrate fully on being "perfect" and they forget to enjoy the song they're playing.
