They're Playing Our Song (2000)

When the owner of KACL decides that each show requires a special theme jingle, Frasier struggles to think of one. Still trying harder, Frasier cancels dinner with Niles, and when he reveals why, Niles is interested and offers to help. Making the tune extremely complex, Frasier enlists Niles as the announcer for a dramatic monologue. Meanwhile, when brushing his teeth, Martin invents a catchy little tune for Frasier, who dismisses it instantly. Still thinking something is missing from his tune, Frasier hires an orchestra and choir to perform in it. He has also promised Roz's new boyfriend Leon a role, eventually giving him the part of lead triangle . Daphne, Kenny and Martin arrive and join Roz to listen to Frasier's long-awaited song. At the end of the two-minute piece (which combines a Broadway musical-style chorus with an incongruous film-score background for Niles' monologue), Kenny is momentarily awestruck. He then explains he did not want something so elaborate. Daphne talks Martin into singing his ditty. Kenny loves it and tells Frasier to come up with something more like that. Starting again, Frasier hears Martin's jingle for the second time. He adds extra words to it, from Martin's advice of "saying what you do". He comes up with another catchy jingle which Frasier hates at first, but he eventually relents and adds his own words to it.

Cultural references: Niles reminds Frasier how he once wrote a musical at school, and lifted the music from Beethoven's Symphony No. 9, notably the setting of "Ode to Joy" in the final movement. Before performing the orchestral jingle for Kenny, Frasier offers his thanks to Calliope, the Classical Greek Muse of epic poetry whose name means "beautiful-voiced".
