This is my best attempt at transcribing the tune by ear from the record.

S:LP: The Dubliners in Concert, Hallmark SHM 682
M:2/4
L:1/8

HG2 Bd | d/d/d eg | aHb z1 a | ge (d/B/)d |
w: man, When the mi-li-tia was-n't want-in' He dealt in hawk_-ing

The sleeve notes on the LP says:

This is a Dublin slang song which Ronnie learned from his father. "Hawking twang" means bartering home made toffee; a Mot is a woman - wife, sister, sweetheart or whatever.

So did I get it right? And does either tune resemble "Limerick Is Beautiful"?
