Vote! Your favourite Eurovision song from Ireland - Round 4!

This is a random round - if you can find a common thread in these songs, you're something of a genius (aside from being Irish and in Eurovision, obviously).

So, in chronological order, first up, from 1967, is Sean Dunphy with If I Could Choose. Sadly, youtube doesn't have the whole performance, so you'll have to make do with a mini-soundclip in this Contest roundup (he pops up around the 6 minute mark).



Next, from 1975, it's The Swarbriggs - minus their 2. Here's That's What Friends Are For.



And now, from 1979, here is Cathal Dunne with Happy Man.



And, lastly, from 1993, the second of Ireland's famous three-in-a-row victory, Niamh Kavanagh with In your eyes. This was voted Ireland's favourite Eurovision entry a few years ago - will it be your favourite?



So, Millstreet calling, etc. Please leave your votes in the comments.
