i would second the Greg Brown suggestion..
he has sevedral songs with fish or fishin'
in 'em. and he does a hilarious monologue
about a fish in a proper british accent
laughing at a lure, not being fooled by it..
saying "Well, I hawdly, think so..." you
get the impressions this big fish has a
top hat, a walking stick and a cigar, p
perhaps.

Greg also does a great one about two boys walking
down main street in their P.F. Flyers (shoes)
carrying 2 5 pound bass, making grown men liars
(the ones who said there aren't any fish in there..)
it starts out " a little crick you could spit across"


he ahs another one about a base ball player who is retiring
and wants to move to a place by a river: (chorus)

So goodbye to the bus. Good bye to payin' dues.
Goodbye to the cheers, and goodbye to the booze.
well I'm trading in this old bat, for a fishing pole.
I'm gonna let the Laughing River, flow right into my soul.
