I've been listening to this song in my head, "mrsmac", and I'm pretty sure Len Graham sung it under the title "Ye Lovers All", which was also the title of one of his solo records on the Dublin "Claddagh" label. I don't actually have that recording, but maybe someone else can help you if they know the song under that title, or perhaps someone might have the recording and can get the words for you from there. I hope it's the same song – I wouldn't have described it as "lively". Good luck.
