"There’s No One As Irish As Barack O'Bama" is a humorous folk song written in 2008 by the Irish band Hardy Drew and the Nancy Boys, (now called The Corrigan Brothers) and set to a tune derived from a traditional air.

Main Street, Moneygall where in Ollie Hayes' pub the song was first performed. The song celebrates the Irish ancestry of the President of the United States, Barack Obama, whose roots have been traced back to Moneygall in County Offaly, Ireland in the 19th century. Moneygall has a population of 298 people. Obama had previously remarked "There's a little village in Ireland where my great-great-great grandfather came from and I'm looking forward to going there and having a pint," prompting the Irish Taoiseach Brian Cowen - also a native of County Offaly - to invite him to do so.


Here's a copy of Obama's Irish roots:

I knew it! Don't worry Barack, I don't have red hair either. :)
