Had a feeling Jim would get there before me!

Excellent job, Jim.

I think the second line of the chorus is:

Only just a 'alf a pint;* I've got a *pain* just here

(Presumably he wants the beer to relieve his agony!)

Third line of second verse I make:

Come round tonight and take the pledge, Bill answered, "Yus, that's me."

I'm not sure at all about the third line of the first verse, but it sounds to me like this:

And he's not at all particular if he spots some *you embar*.

I looked up embar and it means to imprison as in put behind bars. Doesn't make a lot of sense!
