Musicality of Live Performances of Somebody to Love

I've watched a lot of live versions of StL and I've come to like the live versions (specifically Rock in Rio night 1, both ones from Vienna 1982, and Milton Keynes 1982) more than the album version. I was wondering if someone could provide me a link to the sheet music for the backing vocals (if not the entire thing) for the live performances. Thanks!

Best one is from Stockholm '78 though.

Bowl is the best one. Its sad that that performance not ended with the screaming yeaaaah from Roger.

No, no, no. Montreal '81 is the best one.

While all this is great, this topic has already been discussed in another thread, and my question still hasn't been answered yet.
