It's been covered by country, blues, and rock artists, including ...
The Steve Miller Band (1983):
Alan Jackson (1993):
David Lindley and his band, Ex Rayo-X, took it in a different direction (of course!), with Mister Dave playing steel guitar.
Here's the studio version, from 1981. If you were learning to play steel, as I was at the time, you couldn't have hoped for anything better.
We also have three live versions from Mister Dave and his friends. The first is from Rockpalast (1982):
Here's one from Washington, D. C. (1988):
And here's one from 1999, with an all-star cast including Bonnie Raitt, Jackson Browne, Shawn Colvin and Bruce Hornsby:
Everybody sings it a little bit differently, but here's the main idea:
If I had money, I tell you what I'd do
I'd go downtown and buy a Mercury or two
I'm crazy 'bout a Mercury
I'm crazy 'bout a Mercury
I'm gonna buy me a Mercury and cruise it up and down the road
The girl I love, I stole her from a friend
He got lucky, stole her back again
'Cause she knew he had a Mercury
She knew he had a Mercury
I'm gonna buy me a Mercury and cruise it up and down the road
Hey now mama, you look so fine
Ridin' 'round in your Mercury '49
I'm crazy 'bout a Mercury
I'm crazy 'bout a Mercury
I'm gonna buy me a Mercury and cruise it up and down the road
My baby went out, she didn't stay long
She bought herself a Mercury, come a-cruisin' home
I'm crazy 'bout a Mercury
I'm crazy 'bout a Mercury
I'm gonna buy me a Mercury and cruise it up and down the road
If I had money, I tell you what I'd do
I'd go downtown and buy a Mercury or two
I'm crazy 'bout a Mercury
I'm crazy 'bout a Mercury
I'm gonna buy me a Mercury and cruise it up and down the road
I'm gonna buy me a Mercury and cruise it up and down the road
