Wheel’s On Fire was one of the Basement Tapes collection, which he apparently didn’t intend to put out as recordings, so his manager touted a lot of those discarded songs for others to record. Songs like the Mighty Quinn, Too Much of Nothing, Keep it With Mine, You Ain’t Going Nowhere, If You Gotta Go, etc then provided hits for the likes of Fairport Convention, Manfred Mann, The Animals, The Byrd’s and others. As you say, many people wouldn’t know they were Dylan songs.
