Max is our dog's name.... And he is our boy...hence maxboy. The numbers at the end mean nothing. We also have Sadie... AKA Sadie girl... but not before the handle was created.

When I was in music school in the late 70's I composed a piece of music for solo guitar.  It was somewhat in the style of the preludes of Francisco Tarrega so I attributed it to the imaginary turn-of-the-century guitarist Tostados Unidos.  Title of the piece is "Cancion do los Chicharrones."
For some reason it popped into my head when the empty box stared at me, asking for a user name for Audiogon.

I hope it's obvious: a conflation of Bach and Beethoven!
