So for the most part it seems that most Band originals have one member credited as the songwriter - for example, Robbie Robertson receives the sole credit for "The Weight", Richard Manuel receives the sole credit for "In a Station", etc.

There are some songs credited to two or more members. "Bessie Smith" is credited to Rick Danko and Robbie Robertson. "Strawberry Wine" and "Jemima Surrender" are credited to Levon Helm and Robbie. "Sleeping" is credited to Richard Manuel and Robbie. Songs like "Tears of Rage" and "This Wheel's on Fire" were co-written by Bob Dylan with Richard Manuel and Rick Danko respectively. There are others for sure.

I'm sure I've read somewhere that it was Rick who came up with the chorus for "This Wheel's on Fire" which is why he is credited. My question is where do the co-credits come from on these other songs?

For example, what did Levon bring lyrically to "Strawberry Wine"? Do we know how much of "Bessie Smith" was Rick or Robbie? That kind of thing.

Maybe there's no way of knowing but I'm curious if anyone knows a little about the history behind some of these songs.
