No need to be so sensitive about mangling Irish. After all, you'd probably happily sing Frere Jacques without worrying about mangling French - I would, anyway! Or Alouette!

The thing that's really damaging Irish is the reverential attitude to it. As they say: Is fearr Gaelge briste ná Bearla cliste - better broken Irish than too-clever English.

Here's a rough pronunciation of the chorus:

shool, shool, shool aroon
shool guh sucker oggus shool guh kewn
shool guh jee un dhurrus oggus ailig lum
iss guh daren thoo a voorneen slawn.

It's a pity Raidió na Life isn't online: the Dublin Irish-language radio station has various presenters speaking Irish with different accents, including one with a beautiful Spanish accent. Don't be shy. Talk the talk.
