Personally I would have chosen California to go on the album instead of Black Crow Blues , but if that had happened we would be talking about the great lost Black Crow Blues instead of California so it doesn't really make much difference in the long run. The Highway 61 Interactive CD presents yet another previously unheard version of the same song. The real jewel of the Grogan acetates, however, is the appearance of Mr. Tambourine Man with Jack Elliott singing harmony on the chorus. This was the version used as a demo by the Byrds. The reason why it doesn't appear on the album was because it was felt that Elliott's vocal wasn't strong enough.
Sound is excellent - studio quality.
