it's a rule...the memories that get to your brain first get the good spots to hold onto. Memories that arrive later have to share standing-room only handholds and get knocked loose sometimes.

I can remember stuff I haven't sung in 15 years better than something I practiced hours last week.

And I'd prefer NOT to know that song 'X' is almost like song 'Y', thank you....if I start one, I can 'usually' not head off into another one! (I do NOT know how fiddlers and concertina players do it!)((well, yes, I do...many false starts))
