The Beatles - Slow Down (from Past Masters 1)

This song is basic 12 bar blues, so it's Riff 1 4 times,
then Riff 2 x2, then Riff 1 x2, then Riff 3 once, Riff 2 once
and Riff 1 two more times.  I haven't tried to tab the rhythm, 
but it's pretty easy to here from the record.  Sometimes
(mostly in verses) Riff 3 and then the Riff 2 that's played then
is replaced by Riff 4.
This song is not hard but it is fun.
