Better take a closer look at the Mick Jagger signature you worked so hard to get: after 50 years in rock & roll, the Rolling Stones singer has learned that it's entertaining to sign every 10th autograph with the name "Doris Goldblatt" – at least according to the Top 10 list Jagger delivered last night on the Late Show With David Letterman. The list also included jokes about new albums, trashing hotel rooms, Maroon 5 and reverse mortgages, which Jagger gamely delivered with a bemused grin on a stage where the Stones had first performed in 1964.
