When was "Lizzie and the Rain Man" written?

1975, Kenny O'Dell and Larry Henley collaborated on Tanya Tucker's chart-topping "Lizzie and the Rain Man";

1975 is when the most famous version hit No.1 (for Tanya Tucker), but Larry Henley (the songwriter) had his song recorded by Alex Taylor and The Hollies before Tanya Tucker did her version.

According to him, the song was actually written sometime in 1971.

If what I came across is accurate here's when--
It was written in 1971 by Larry Henlye and Kenny O'Dell.
It was based on the movie The Rainmaker.
It was also recorded by Alex Taylor, and the Hollies.

Tanya Tucker's version is the most famous..
