Ok I've done some digging and I've found something. On his obituary on Legacy.com, someone who claims to have known Lee Groban says that they have a copy of The Cure for Insomnia and will treasure it for the rest of his life. That quote makes me think he'll still have it. Here's the page: https://www.legacy.com/us/obituaries/chicagotribune/name/lee-groban-obituary?id=2622431. I need some help because the only things listed are his name, Bart Bukwa, His location in Evanston, IL, and the fact he was 9 in 71 so was born in 61 or 62. I'm not amazing at finding people so if anyone can please help me look for him as he may have one of the only copies left.
