Here is what I am now doing with song form markers: It is important that your songs are unfolded. I assign song form makers a little differently than ABC etc. I use the following letters:
I=into
V=verse
C=chorus
B=bridge
P=prechorus
E=ending

This way I can think in terms of verse, chorus, etc. YMMV

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"
