From reading Robert Gordon‘s excellent biography of Muddy Waters – Can’t Be Satisfied – I learned that the former McKinley Morganfield once made a little pocket change recording a radio spot for Dr. Pepper:
Is it really true – as the YouTube video clip contributor asserts – that Randy Newman wrote this blues jingle? Could it be that this very same radio ad can be found on a rare piece of promotional vinyl, Dr. Pepper: The Most Original Soft Drink Ever – Original Cast Album?
This Dr. Pepper album sold for $50 in a 2010 Ebay purchase and is described on Popsike (online archive of rare vinyl auction sales) as “RARE Muddy Waters Randy Newman.”
I have no idea who wrote it. We weren’t told. I do remember it was recorded at Chess Studios in Chicago and I played a bass line/ rhythm guitar part that you can hear clearly on the right side that led the band through very strange non-standard Blues changes. Trying to get Muddy to sing the right words over it was not easy. We did get it though, and I think Muddy’s belligerent voice singing those words is very…weird and funny.
