Flanging Firsts and Faves

Beatles did it.
Eagles did it.
Even the dudes in XTC did it.
Flanging, sometimes called phasing, is the strong spectral alteration of a swept comb filter created by a modulated short delay. Recordingology has two pairs of questions for you, all about flanging:
1. Was Miss Toni Fisher first, or can you find an example recorded before 1959?
and
2. What’s your favorite recorded example of flanging, and why do you think it works so well in that musical moment?
