In my view this was just a silly little song that the writers put into Alice in Wonderland to be funny, although the mouse seems to be drunk which in that case would be somewhat inappropriate for a children's movie so they added a funny little ditty to draw away from that fact and not to mention you can't get drunk off tea.

Private Malone bought the car new and went to fight in the Vietnam war leaving it behind Malone died and never returned to the car. When the young soldier bought the car for $1000 years later he finds Private Andrew Malone's note to the future owner telling them to make the car their own but that Private Malone would still be riding along. He also said that the car had been a dream of his but it had been shattered now it was the young man's dream. After the young man had fixed the car up he later took a curve to fast and crashed and witnesses said that a soldier pulled him from the wreckage and the young man finally knew it was true and that he had always been Ridin with Private Malone. This song has so much meaning and I wouldn't mind having a car like that 1966 Corvette who came with a hidden guardian angel.
