Obviously, he isn't Freddie, but who is (besides Freddie!)? I think they do a good job with it. It's the best non-Queen version I've ever heard of Dragon Attack, but I don't get out much!!
Don't get the wrong impression. I'm sure some say the vocal sucks because they think it does. And yeah, there will be others who just don't like hearing someone else sing those songs.
Personally, I don't like the guy's voice because of the thin sound, the bad technique and the cheesy 80's vocal tone.
The band, though, are real good.
Peace,
Adam.
