You are one of my favorite journalists.
And this is a very good column.
(a) Don’t begin a column with a Led Zeppelin “quote.”
(b) In this instance, it was indecent to pretend this song was not written by black Americans. Specifically, Memphis Minnie and Kansas Joe McCoy.
(c) If you need a quote for a New Orleans column, please consider getting it from a New Orleans musician. I’ve heard they have some there. Chris Thomas King’s “Baptized in Dirty Water” would have been a nice choice.
