The tune of Preab San Ol is already in the DT for the song Dublin City (Union) by Donagh McDonagh (filename [DUBLCITY.) But I personally feel that it goes better to the tune of Boolavogue.
AKS - I can give you a phonetic version of the Dubliner's second verse if you like, then maybe someone else could translate it into real Irish - and English!

Ishamer thleave yer sa ga lily steerber, geegad gwisker gallerchroin
Solomon creerner inner chollereer hole, knee vair shangaber dachonir galore
O'Neill se tailshuch, ma shonongweeher, 'n slum na squealer, no slum'n chyo
Mashi narishi neel bat neer skreerner, na varishiri vair chyle Preab San Ol.

(The pronunciation/spelling is basically English, but 'ch' is always hard as in Scottish Loch, and 'thl' in line one is more like a Welsh 'LL'. And no, after more than thirty years of listening to it, apart from 'Solomon' and 'lily', I don't know what any of it means

Wassail! V
