Thurl Ravenscroft, the amazing baritone voice of the Haunted Mansion’s Ghost Host and Tony the Tiger (among others) recorded an album of gospel, called “Great Hymns In Story And Song.” The Basic Hip Digital Oddio archive has MP3s of every track on the disc. (Lots of other great stuff on this page — Gershwin performed on bongo drums, vintage IHOP and Sears radio ads, and nice linkage).
As Brett points out, the Ghost Host is voiced by Paul Frees — Ravenscroft’s contribution to the Haunted Mansion was as the lead baritone in the theme song, “Grim Grinning Ghosts” (he’s the singing bust that bears a striking resemblance to Walt Disney)
