Get on a TWA to the promised land.
Every woman, child and man
Gets a Cadillac and a great big diamond ring.
Don't you know you're riding with the king?
The reference here is twofold; first to the Chuck Berry song, Promised Land that was made famous by Elvis, and second to the penchant Elvis had for very large diamond rings and Cadillac cars.
TWA was a major American airline, in business from 1925 until 2001 when it declared bankruptcy in the wake of the September 11th attacks.
