PHLO meaning in Community ?

The Pigsty Hill Light Orchestra (or PHLO) were an eccentric band of British musicians, who joined together in early 1968 to play a fusion of comedy, jazz, and folk music, in a unique style which has been compared with The Temperance Seven and the Bonzo Dog Doo-Dah Band. Much of their repertoire consisted of songs from the 1920s or 1930s. Other influences included music hall, blues and jug band music. Their eccentricity arose, not only from their characters and choice of music, but from an eclectic mix of instruments, some of them home-made, such as the 'egg-cupaphone' and the 'ballcockaphone' - a wind instrument in which the supply of air to the reed was controlled by a toilet cistern chain connected to a ballcock.
