From Monty Boyce although it'd take a LOT of bollocks to busk it.

Depeche Mode and Jesus and Mary Chain both came up with some beautiful "pop-songs" but in extremely dark production.

I'd happily lay down money to anybody interpreting something like Personal Jesus or Never Understand on unaccompanied acoustic.

Edit - For a crowd pleaser (subjective as I'm an unreconstructed Ska boy)-Message To You Rudi, or possibly The Mighty Mighty Bosstones - The Impression That I Get. Both relatively easy if you translate the brass section into rythym.
