Name That Tune

Being away from my music for a few days has a predictable effect on me. I invariably develop an ear-worm to enjoy (or even two) and today I've been happily finding myself running through a fair chunk of Van der Graaf's Aloft from Do Not Disturb. Now can't wait to get back to the real, solid thing. Not sure this is what I should be reflecting on in the middle of a serious discussion of educational possibilities, but one can't stay on task all the time, can one?
