Could this be the song you heard?

Transcribed from a sound sample at RVsongs4you:

WALTZING THROUGH WAL-MART
Cliff Rodman

We're waltzing through Wal-Mart while parking on their lot,
Staying where the camping is free.
Out come the slides, the chairs, and the fake grass.
We're setting up our RV.
Folks are a-starin' but we ain't a-carin'.
The satellite has its own parkin' spot.
We're waltzing through Wal-Mart, parkin' on their lot,
Staying where the camping is free.

We're waltzing through Wal-Mart, shopping till we drop.
We're happy as we can be....

[As sung by Cliff Rodman on his album "RVsongs4you."

[Note: the song as recorded does NOT use the same tune as WALTZ ACROSS TEXAS, but I think it could be sung to that tune, although the scansion leaves something to be desired. Whaddaya wanna bet, the writer first conceived of this song as a parody of WALTZ ACROSS TEXAS, but then changed the tune, and maybe the title, to make it sound more original?

[Cliff Rodman, by the way, has a very nice, mellow voice.]
