[3] "Still a Fool", recorded by Muddy Waters a year later using the same arrangement and melody, reached number nine on the Billboard R&B chart.

Petway's was the first to be titled "Catfish Blues" and is sometimes cited as the basis for Muddy Waters' "Rollin' Stone".

[5] "Rollin' Stone" has been identified (along with "Walkin' Blues", the single's B-side) as one of the first songs that Muddy Waters learned to play and an early favorite.

Called "a brooding, minor-hued drone piece",[6] "Rollin' Stone" is a mid- to slow-tempo blues notated in 4/4 time in the key of E major.

[1][8] It did not reach the national record charts, but sold about 70,000 copies[8] and allowed Muddy Waters to quit his day job.

Subsequent versions of "Rollin' Stone" or "Catfish Blues" often use some lyrics from "Still a Fool" (sometimes called "Two Trains Running" after the opening verse).
