Thank you Marion. This should possibly be a permathread.

Concerning playing with records (which I have also started doing, and is a good tip) I have noticed a couple of problems (maybe some of the sages here can help):

I notice that a number of records don't actually fit any of the keys -- I assume that is because they were speeded up or slowed down in the recording process. It is a mild irritant, but I haven't figured out a solution -- I don't have a system that slows fractionally (does anyone outside of a studio?), and the solution that did occur to me, which was tuning down or up the guitar a fraction from standard E or whatever is just too hard for idiot ears like mine.

One gets too ambitious or too discouraged really quickly doing this. You have to restrict yourself deliberately to just hearing the chords change or keeping strict time. Which is tough, given the temptations. Good thing to do though.
