I used the same technique for years. Had a song I could cite for just
about every interval.
>> The #4th is more uncommon but I have one: the first two notes of The
Simpsons
>> theme... (The Siiiimp...).
I don't know the Simpsons theme song (never cared for the show), but for
the sharp 4th I use the first two notes of the song Maria (from West Side
Story). BTW, Maynard Ferguson's recording of this song in the early 60's
is still my favorite version. I think it was arranged by Don Sebesky (or
was it Willie Maiden?).
