I know this isn't exactly on topic, however I just found an amazing video few people have seen, a live performance of Alive from 1988, definatly the best toshi has sung it live, he does at some points sing the song a bit higher then he has on the other live vids we've seen, mostly at the beginning though, anyway here's the vid.
