Cover art for Mercy Buckets lyrics by Drive-By Truckers

I have no idea if there's any back stories to this song but for some reason I see this as a father telling his daughter that he'll always be there and be supportive but it could be a wife, girlfriend, mother or just a friend (I assume female because of the put a smile back on your pretty face" line). No where near the best DBT song but I love almost everything they do.

I read an interview with Patterson, and he said Mercy Buckets is redneck for "Merci Boucoup". His sister used to use to always say mercy buckets to him as joke. As far as the song goes, its a pretty clever way to use an inside joke, and I think it refers to that person you have in your life that you can count on no matter what.
