I may be going soft in the head but the Mormon Tabernacle Choir's rendition of Bob Dylan's Blowin' in the Wind isn't completely ludicrous. In fact, I just purchased the 10 cent stream at lala.
From a 1990 Argo recording Songs from America's Heartland. Well, I suppose Dylan is technically from the heartland. Less sure about Paul Simon though...
Wikipedia on Blowin' in the Wind: Although it has been described as a protest song, it poses a series of philosophical questions about peace, war, and freedom without supplying concrete answers. The refrain "The answer, my friend, is blowin' in the wind" has been described as "impenetrably ambiguous: either the answer is so obvious it is right in your face, or the answer is as intangible as the wind"...In 2007, Pope Benedict XVI...wrote that he was uncomfortable with music stars such as Dylan performing in a church environment.
