Are we really sure that Belafonte recorded the "sifting sand" "Mary Ann"?

There's a Bear Family Records box set titled Marianne by the Easy Riders. Notes were written by the estimable Mary Katherine Aldin, who sometimes posts here at Mudcat. The Easy Riders Discography in the CD booklet says that the song "Marianne" was written by Gilkyson-Dehr-Miller, and recorded by the Easy Riders on May 31, 1956 [ the members of the Easy Riders were Hamilton Terry Gilkyson, Richard James Dehr, and Frank Miller].

We have a couple of songs posted above that appear to be traditional antecedents of the Gilkyson-Dehr-Miller song. I found recordings of the song by the Brothers Four and by the Highwaymen, but no sign of a Belafonte recording. The person who sings lead on the Easy Riders recording sounds a lot like Belafonte - maybe people just think Belafonte recorded it.
