To prove to myself that it really did work, I set up a radio channel on a PC on one of the jazz stations and the first tune that popped up was the old Saturday Club (with Brian Matthews) theme. Miles Davis, Milestones. Hairs on the back of the neck moment - until then, I hadn't known what it was called.
Julie London - Cry Me a River, Acker Bilk - Deep Purple, Bobby Darin - If I Were A Carpenter, lots of memories with these and many others*.
Duane Eddy - Peter Gunn, ALWAYS want to turn it up to eleven.
Nina Simone - House Of The Rising Sun, for the goosebumps.
Weird Al Yankovic - Money For Nothing (with the words from the Beverley Hillbillys Theme, strangely, it works better than the original), just because.
Dave Brubeck - Take Five
Not sure about the comfort zone thing, just stuff that I would include on my solar powered mp3 player should the need arise.
*Many Others, little known Jewish session saxophonist, but often gets a mention in the credits.
