Jimmy Murphy also does a bluesy 'Louise', probably from the same rootstock as McDowell's - the opening lines and melody are similar. It is on his classic 'Electricity' album which has been reissued to CD on Sugar Hill SHCD3890. The CD booklet has an excellent essay by Dick Spottswood but makes no mention of Murphy's source for 'Louise' - it is simply credited 'PD'.
