The plastic comb binding (where pages can be replaced) is GBC.I have all my versions/transcriptions of songs that I do, wish I did, think I might want to do, etc. in electronic version and archive these printouts in 3-ring binders. I have a separate folder for stuff I'm working on, and sometimes (often) run out songs to learn or refresh my memory of at work in between jobs. (My boss didn't hear me say that, did he? The people at work seem to cope well with my singing odd songs at strange times.)
Ah well, it's Friday and there's a session and a black and tan in my future at The Press Room.
