It may be that it's no more than a title but I find this at Archive of Misheard Lyrics (search 'G,' Guantanamera:

The real lyrics were:
Guantanamera, guajira guantanamera

But I misheard them as:
One ton tomato, I ate a one ton tomato.

[James McIntyre says: Michael Nesmith (of the Monkees) had a television show on ABC that ran for six episodes in the late 70's or early 80's called "Elephant Parts". The entire song was parodied, with the "one ton tomato" lyric included. I also remember that as a visual accompaniment, a large tomato fell on Mr. Nesmith.]

And I find Somebody Bit The Moon, album by Sherban Cira, reviewed March 1997 - includes, they say, his signature tune, "One Ton Tomato."

There's also a set of lyrics at Wayne Read but I don't think this one counts.
