This is #2 from PDQ's "The Art of the Ground Round" (S.1.19/lb)(S stands for Schickele number).. for Three Baritones and Discontinuo.
Unfortunately the music is available through Theodore presser Company, # 312-41055 (for some reason, i just happen to have two copies!)
# 2 is entitled "Please Kind Sir", written for two parts and needs to be sung as written to have the proper effect of the music.
From the music notes:
The Art of the Ground Round is uniquely typical among PDQ's works especially in its use of the discontinuo. Most baroque pieces had a so-called continuo part, which sonsisted of a bass line with the chord symbols, to be played by a bass instrument and a keyboard; the left hand on the keyboard played the bass line and the right hand improvised on the basis of the chord symbols. PDQ Bach's problem was that toward the end of his life he got so fat that he couldn't reach the keyboard simultaneously with both hands. So he simply played the bass line and forgot about the improvising (which was the harder part anyway), or probably more often didn't play at all, leaving the bass line to the bass instrument and himself free to drink beer.
Most of the rounds in The Art of the Ground Round are of atype fancied by certain sixteenth and seventeenth century English composers: they reveal, when sung together as a round, levels of meaning that are not apparent when the parts are sung individually. whether PCQ knew what he was doing, or whether the hidden meanings were accidental, is a moot point, as is almost everything he ever did. In fact, one of the many revolutionary aspects of this much and understandably neglected composer is that, years before the blossoming of romantic "atmosphere" record albums, PDQ Bach was writing moot music.
Other rounds in the set include: Loving is as Easy; Jane, My Jane; Who, Oh Who; Golly, Golly, Oh; and Nellie Is A Nice Girl.
