The last few days haven't been easy ones for David Letterman, naturally. Ironically, though, the scandal may end up benefiting Letterman's right-hand man, Paul Shaffer. The Late Show's longtime band leader's new memoir, We'll Be Here For the Rest of Our Lives: A Swingin' Show-biz Saga, officially goes on sale tomorrow. And while the "candid" book that takes readers "behind-the-scenes" doesn't contain any revealing info about Letterman—or address any of his dalliances with junior staffers—the book is selling briskly and has secured the No. 1 spot in Amazon's TV category.
