The Flying Phlegm
Punk-looking but rock-sounding high school band playing a battle of the bands at Charlie's Meet Rack from the teen film Lovelines (1984). They sing "Ba Ba Baby." The MC introduces them as Dragon and the Flying Phlegm, but the soundtrack lists them as The Flying Phlegm.
Members include drummer Dragon (Miguel Ferrer) and singer/bassist Tongue (David Jolliffe).
