Lyrics copied from the Cowpie address given above:

IF I HAD A PONY
(Lyle Lovett)

CHO: If I had a boat, I'd go out on the ocean.
And if I had a pony, I'd ride him on my boat.
And we could all together, go out on the ocean,
Just me upon my pony on my boat.

And if I were Roy Rogers, I'd sure enough be single.
I couldn't bring myself to marryin' old Dale.
It'd just be me and Trigger. We'd go ridin' through them movies,
And we'd buy a boat and on the sea we'd sail. CHO.

Well, the mystery masked man was smart. He got himself a Tonto.
'Cause Tonto did the dirty work for free.
But Tonto, he was smarter, and one day said, "Kemosabe,
You can kiss my ass. I bought a boat. I'm headed out to sea." CHO.

And if I were like light'ning, I wouldn't need no sneakers.
Well, I'd come and go whenever I would please.
And I'd scare 'em by the shady tree, 'n scare 'em by the light pole,
But I would not scare my pony on my boat out on the sea. CHO.

Just me upon my pony on my boat.
