The Pike song is one of those on-V-as-the-first-half-of-the-progression-ends songs that were so popular in the 19th century.

One of the people who claimed to have known "Alabama Bound" the earliest (before about 1900), Alf Valentine, sang it implying I-I-I-I-V-V-V-V-..., rather than the I-I-I-I-IV-IV-IV-IV... we usually hear for the song.
