Seashores of Old Mexico is a studio album by Merle Haggard and Willie Nelson.

[1] Haggard and Nelson, who would each be plagued with financial problems in the years ahead, chose to produce the album themselves.

Perhaps the biggest surprise on the album is the inclusion of the Beatles classic ballad "Yesterday", a song that Nelson had performed regularly in concert in the sixties but Haggard had cited as a marker of the end of the good ol' days on his 1982 hit "Are the Good Times Really Over (I Wish a Buck Was Still Silver)."

At times the album sounds like a Merle Haggard record with Willie Nelson on hand as support.

"[2] In his 2013 book The Running Kind, Haggard biographer David Cantwell is especially critical of Haggard's singing on "Yesterday": "His rich baritone, in especially fine form on Seashores' every other track, feels like it's been unexpectedly pumped with air and left out overnight in the chill and damp.
