This happens to some degree in our band for diff reasons. At first we were learning sp many so fast, we made some goofs. Sometimes a new guitarist comes in, play it slightly different and i dont feel like fighting it. But what i will NEVER tolerate is playing Folsom as a 12 bar, when its really an 11 bar. Its the tiny things sometimes that really make a song what it is. Fought one guitarist on this tooth and nail. I had to nod him all the time.
