Old blues - a shameful confession

This is a shameful confession but I can’t listen to old blues songs (see http://terrapinlistens2.blogspot.com/2009/04/some-pre-war-blues.html) without subconsciously imagining what they would have sounded like played by Led Zeppelin. For example, Willie Brown’s “M&O Blues” is superb, but my mind’s ear can hear John Bonham’s drums crashing in at the end of the first verse. I will persevere.
