why so many testicular comments? i've sing a lot in falsetto and find it a lot easier on the heuvos than full-voiced high notes, you know?i developed a decent falsetto by singing along with one of my favorite rock and roll bands--trip shakespeare. they sung a lot of really good, high, high harmonies. go get their record "across the universe" and sing a long (you may have to look at the local used cd store as these guys haven't been together in years...)
