We've had several versions of the lyrics posted. This one, I think, is definitive:

(Get Your Kicks On) Route 66 [Bobby Troup, 1946, Londontown Music] If you ever plan to motor west, Travel my way, take the highway that's the best, Get your kicks on Route Sixty-six! It winds from Chicago to L.A., More than two thousand miles all the way. Get your kicks on Route Sixty-six! Now you go thru St. Looey and Joplin, Missouri, And Oklahoma City is mighty pretty. You'll see Amarillo, Gallup, New Mexico, Flagstaff, Arizona, Don't forget Winona, Kingman, Barstow, San Bernardino. Won't you get hip to this timely tip? When you make that California trip, Get your kicks on Route Sixty-six!

Bobby Troup (1910-1999) was married for forty years to Julie London. He acted in several movies, and was Dr. Joe Early in the television drama Emergency from 1972-1977.
Troup also wrote the song "Daddy," recorded by Eartha Kitt.
