It'd be cool to know if there are any guys out there who enjoy singing up *there* ?
I'm a bass-baritone, but I think my falsetto is quite well controlled. I might even say that I count myself as an alto

Anyway, recently, I've had this obsession with Bach arias and anything alto-related.

just want to know if i'm alone in the world, or not !

LOL! You're not alone. Many tenors that I know, including myself, love singing "up there", in falsetto obviously. I can reach a high C...soprano above the staff falsetto, but, i mean, i've never come a cross a guy who could sing high withough falsetto....a song i sang called O Sifuni Mungu had a tenor line higher than an alto line...

Hmmm. I'm looking at my copy of O Sifuni Mungu, but I'm not seeing the tenor higher than the alto. They share the same notes once in a while, but the tenor doesn't go above the alto, unless you have a different version. Mine is arranged by Roger Emerson.
