I think you're right, although it was more prominent when he was younger. Just listened to the Sirius/XM special of him in my car. Seemed like a decent fellow, who did a lot of charity work. His daughter was singing with him during the latter part of his career. RIP.Not a favorite, but I did buy his album back in the day because I liked his tunes. Do I remember him wrong or did he have a weird sort of "camel mouth" like Buddy Hackett?
