“I’d Jump the Mississippi” was written by George Jones and the country songwriter Johnny Mathis. Jones recorded it with Melba Montgomery in 1964, as part of a duet album with a bluegrass cast.
The song is a duet of extravagant devotion. To prove his love, the singer says he would do the impossible — even jump the Mississippi River — and the song turns on that cheerful, tall-tale exaggeration of what love would drive a person to do.
The song’s bright melody and duet form suited bluegrass.
