You are absolutely correct! Just before he begins singing. Hard to believe they left that in, it's so egregious. If memory serves, this is one of the Minneapolis re-recordings that Bob and his brother did with some local musicians hired at the last minute, so they obviously weren't familiar with the songs. Still, the results they got with "Tangled Up In Blue" and "If You See Her, Say Hello" were huge improvements over the original NYC versions. On this cut, however, I don't think the re-take worked so well -- although that bum organ note could be the only reason I think this.
