Hi Tracy:
I don't spend much time on other folk's lyrics... but the title you picked certainly struck a chord. I wish I had a nickel for every time I've heard that expression.
I tend to agree with Wes, sometimes the "Money Line" can be expressed too often. I'll suggest you consider only three lines per verse... ending with... "xxxx-xxx and the horse you rode in on!"
After thinking about the cowbells versus "bang-bang"... I can't make my mind up about what sound effect will work most effectively... but if I have any bright ideas, I'll share them with you. Maybe something more "melodic" done in a naughty way using harmony between a score of instruments.
To me, that means the first two lines must rhyme and the last line, (the punch line) will simply be repeated in each verse. How it get's handled in the chorus is something I have not yet considered... but I think you have a "winner" here and hope you will keep whittling away at it until it's ready for the runway. Best of luck with it and before I forget... Happy Easter! ----Dave
