John Oates, one half of the popular duo (he's the one with the mustache), will make a special appearance at the Rock Hall at 1 p.m. today. The appearance will include an interview and a book singing. Oates has just penned Change of Seasons, a book about his life. During the interview, Oates will discuss the band’s 2014 induction into the Rock Hall and how traditional American folk and blues and Philadelphia soul shaped the band’s sound. Dr. Jason Hanley, the Rock Hall’s Vice President of Education and Visitor Engagement, will lead the discussion. After the interview and a short acoustic set, Oates will sign copies of the book at 3 p.m. in the FYE store inside the Rock Hall. Advance tickets are required for the interview and performance. Those tickets cost $10. The book signing is free with the purchase of Oates’ book from the FYE store. (Niesel)
