Ray, in the name of all things holy, NO!!!! I beg you not to continue with this folly. There is absolutely no point in compiling the "most popular" Irish songs, coz those have all been done to death. That is what makes them (groan) popular and staples of the rent-a-mick pub band scene. Take this list you've got. Apart from being staggeringly unimaginitive (with all due respect), some of those songs are not Irish, trad or otherwise. Parting Glass has origins in Newcastle upon Tyne, Raggle Taggle has strong Scots links, Whiskey on a Sunday and Leaving of Liverpool are from, erm, Liverpool. As far as Wild Rover and Whiskey in the Jar go, just don't bother. These two old stagers should be allowed to rest in peace. The only songs from your list which deserve a place are Kerry Recruit (definitely) and Botany Bay (probably). Try Andy Irvine's "The Holy Ground", or trad songs like Roger O'Hehir, Edward in the Lowlands Low, or My Charming Edward Boyle.
I dunno who your compilation is for. If it's for you, try broadening your horizons a bit. If it's for friends or non-music types, do them a favour and leave out a lot of that crap - The wild rover was never much good anyhow, and forty years of drunken bellowing hasn't helped matters. I hope you'll take this in the spirit of constructive criticism, rather than as a total slagging. a.w.
