Plenty of unaccompanied singing here on Teesside. Mostly I hear more songs sung unaccompanied than sung with accompaniment, though both are welcomed, at least that's my experience.

Stringsinger's right you don't have to be pitch perfect to sing unaccompanied. It's about putting the song over. Getting the words clear and conveying your understanding of the song is more important than being absolutely on pitch.

I started out singing unaccompanied but I felt that some songs needed accompaniment so after trying various things, I settled on ukulele (I can imagine that being added to Richard Bridge's hate list). I like to have the choice.
