Notes:

• Song has just three chords: A7, D7 and E7. These "dominant 7" chords are great for soloing over.

• Suggested strum:

              D      D      D  U  D
              1      2        3  &  4

(D = down strum,   U = up strum)

• Song is based on a standard 12-bar blues format.

• Written by Bobby Troup 1946 and first recorded by Nat King Cole the same year.

• The original U.S. Route 66 highway was established in 1926 but eventually taken out of the U.S. highway system in 1985. Still, many stretches of the original road can be driven today.
