Bluebird by Robin Trower/James Dewar
I remember when this song came out in 1977; I heard it on the radio one cold morning. It was so beautiful that I lunged up out of bed, then lay back down, listening in awe. It calms me every time I hear it, while overwhelming me with the amazing guitar skills. If you wait past the first few awkward seconds, it'll be worth your time -- the recording is from 1977, so there's a little noise.
Relax, and let it happen. You could even knit while listening!
