Cranky Steely Dan star Donald Fagen has blasted Bob Dylan and his Dukes of September tourmates Michael Mcdonald and Boz Scaggs in a new Rolling Stone magazine article. The 65-year-old rocker reveals he has walked out of several Dylan shows because he finds the folk-rock icon "tedious" and admits he took "certain pharmaceuticals" to help him relieve the boredom of touring with Scaggs and McDonald. Of Dylan, Fagen says, "He has about a dozen minor-key-drone tunes with three chords. I find it very tedious. He actually has songs that are more boring than some early Appalachian songs. It's amazing. "He has songs with 512 verses and almost no melody. I think a psychiatrist would be more useful than a throat doctor at this point." And Fagen also opens up about his experiences on tour with supergroup The Dukes of September Rhythm Revue, which he formed with McDonald and Scaggs in 2010. He adds, "I was miserable... I kept wondering what I was doing out there. But I have certain pharmaceuticals that are legally prescribed that help my various mental and physical problems... Also the mood disorders that go along with touring give you a certain amount of energy."
