I'd agree with any Irish song sung in CW style, but I'd have to expand it a bit - to ANY song sung in CW style, including CW songs. ;-)
But, sorry, still love Maids When You're Young, Wild Rover (yes! - done wistfully), Broom of the Cowdenowes, Wild Mountain Thyme, & Wild Colonial Boy - guess I just don't get to hear them as often as some (honey, I live in IOWA - I don't get to do much of ANYthing as often as some).
Have to agree with hating Waltzing Matilda, Bottles of Beer on the Wall, Teach the World to Sing, Wedding Song, & Happy Wanderer.
Don't know of anyone who ever sang Green Berets SERIOUSLY (just the circles I run in, I guess).
I am kind of sick of Mattie Groves - but I think that's because everyone I ever heard sing it in person learned it from the Joan Baez songbook, & it's just the same old thing again & again, and no one would DARE CHANGE ONE WORD. By contrast, I could listen to Christy Moore's version (Little Musgrave) over & over & over.....(what a difference the right version/right voice makes!)
I don't think The Unicorn is a terrible song - I just got personally sick of it after, having sung it ONCE to cousins I was babysitting, being forced to re-sing it about a google times every time I sat with them. I don't know any kid who doesn't love it.
Agree with ditching those maudlin, supposedly Irish things like When Irish Eyes Are Smiling & all those ditties about "me auld mither."
