Ollaimh, from here: Tom O' Bedlam . Though after a bit more browsing, I think verses from the two songs (ie: 'Tom of Bedlam's Song', and 'Mad Maudlin's Search for her Tom of Bedlam') might be a bit overlapped here, and require a little sifting. In fact I think what most people think of as 'Tom of Bedlam', is in fact more rightly 'Mad Maudlins Search' - as such the alternate chorus I posted above, probably belongs to Tom's Song & not Maudlin's Search! Eh oh!

Interesting factet from Wiki I found about Ms. Maudlin though, apparently "Maudlin" was a form of "Mary Magdalaine" - as the equivalent of the all male 'Bedlam' for women, was the Hospital of St. Mary of Bethlehem.
