“Tulane” wasn’t Chuck Berry’s last great song — that would be “Oh What a Thrill,” from Rockit — but it’s awfully close. Recorded for Back Home, the 1970 album he recorded for his return to the Chess label after a few years at Mercury that we fans are still trying to forget, “Tulane” both sounds like classic Chuck (you have heard this guitar intro before) and completely up-to-date (it’s about a head shop raid). On the album, Berry follows it with “Have Mercy Judge,” one of his sharpest blues performances, the tale of what happened when Tulane got away from the cops but the singer didn’t.
