Again I agree with "meself", but the Gaelic tradition does encourage singing through An Comunn Gàidhealach and the National Mod, where competitions for Male and Female of all ages are held.
The Mod has produced some very fine male singers over the years.
I have been fortunate enough to know several, the first of whom was my old science teacher Neil MacLean(Auld Neilly) in Dunoon Grammar School. He was Mod gold medallist and made several 78s. He used to sing for our class regularly......"put away the books boys, I feel a song coming on" :0)....a gentleman who's first greeting to each new pupil was...."and have you the Gaelic?"
