Not everyone agrees (we can write our own songs,it’s anglifying us, everything should be like it was back in the good days, when Vercingetorix was still a cool dude in Britanny bla bla bla), but I think a good way of saving Gaelic (Irish in this case) is to keep it modern and something that our children can relate to. And if that means translating Lady Gaga, or, as here, a song from Glee, into Irish, then so be it.
