I think it is good to try to sing in other languages, apologizing for the mispronunciations etc. I certainly would not want to keep anyone from singing in English or Latin and would excuse their mistakes. I have an absolutely terrible ear for languages myself, but others are quite capable of doing an OK job. I would like to be able to sing a few songs in Gaelic..I know I would botch them terribly and would have to do it in a written-out phonetic system..which would be painful for native or trained speakers to listen to I know..but it doesn't mean I shouldn't try. But I have sung (painfully badly) in Welsh, German, probably not too badly in Spanish...French..but that is probably my worst attempt. mg
