September 7, 2023 — Creedence Clearwater Revival’s “Fortunate Son” drifts from Karroll Tillett’s workshop, a wooden shed about half a mile from where he was born. Tillett, known as “Frog” to everyone here, has lived most of his 75 years on the water, much of it chasing summer flounder. But the chasing got harder and harder, and now he spends his time making nets for other fishermen at his workshop, at the end of a dirt path next to his ex-wife’s house.
