When I was maybe 10-11 I would buy a music book series called "combo orchs" and get together and play along with my cousin who was 5 years older and quite a bit better than me. He on accordion, me on sax.
Now he at 80 yr. and me at 75 still get together, randomly select tunes from a fake book and have a wonderful time.
Now to respond to the question, there were 2 songs that I remember "learning", Four Brothers and Bill Doggett's Honky Tonk.
