Mine vary depending on what I am learning, so currently 'I can't go for that', 'Josie' by Steely dan (which caused me to learn Peg) and a few other motowns for my group, and cycle through the 40 or so in my main group,, but away from stuff I have to play, there are some I always gravitate to playing that I dont play in groups.
Fool for your loving, Hit me with your rhythm stick, Master Blaster, Schism, Down in the tube station, spirit of radio, December 63, Roundabout and 'something very strange' (last one by Spocks beard, the previous ones should be self explanatory).
