Rockin' is my Business & Business is Good?

I played in a cover band years ago called Subway and we did a remake of a song Whose hook was "Rockin' is my business & Business is Good". The strange thing is the song was recorded by a country band. I thought it was "The Kentucky Headhutners" but it's not on anything they released or recorded. The song Rocks, especially when played by a really good Rock band, and I want to cover it on my next Album(CD for you younger people out there). All I can find is this 50's band with a similar lyric, but it's not the same one. Find it for me and I will give you a credit on the Album(CD or whatever).
