From the wiki: “‘The Seventh Son’, also recorded as ‘Seventh Son’, was written by Willie Dixon and first released as a single by Willie Mabon on Chess Records in 1955 (with Dixon on bass). Dixon recalled (via Songfacts.com), ‘The seventh son is part of the scriptures of the Bible. ‘The seventh son of the seventh son born on the seventh hour of the seventh day of the seventh month.’ I was born in the seventh month and I was the seventh child of my family.’ In the same interview, Mose Allison, who covered the song in 1959, remembered, ‘I thought that was a great song of that type. One of the common things is to feel that you are supernatural sometimes. And most people have felt that at one time or another.’
