Okay, Joe, I've had time to check my indexes. I had already done an in-depth study some years ago before working on the Roud Index and it was obvious then that despite the appearance of a few stanzas of 'Early Early' in 'Trail to Mexico' the latter had enough autonomy of its own to be considered a separate song. There are plenty of American versions of 'Early Early' and some of these have developed their own stanzas, but none of these new stanzas coincide with 'Trail' versions. I have recommended to Steve we give 'Trail' a new number, and if he agrees I will let you know the outcome.
