Thanks! I think mom is worried that they won't see the humour in the cow playing the double bass. XD The lady with the steel guitar is based off Memphis Minnie (she sang the song Hoodoo Lady). She's one of my favourite jazz/blues musicians. :D

Fun fact: When I did the Delta Blues project for Word and Image for Barry (I'm not sure if you had to do that one), I had a cow in that poster as well... only it was on the roof of a shack in the middle of a flood ala Oh, Brother, Where Art Thou? XD
