What would be a good approach to gain a lyrical interpretation of 'So In Love' by Cole Porter?I'll be performing this song soon in an Eisteddford...

I would listen to some of the versions of the song that
have been sung by other artists.  This will give you an idea of what notes need to be
punched more than others and will also give you some idea of the different
interpretations of Porter's work.  Hearing singers like Julie Andrews, Placido Domingo,
Dinah Shore, Ella Fitzgerald, or Patti LuPone will really give you a very nice feel of
the song.  Yet, for my bet, I have a personal love for the version that country song and
icon k.d. lang sang in 1990 on the album, "red+hot+blue."  I cannot help but feel that
if you really want a feel on how this song should be sung, listen to her version.  It's
great because it captures the precarious combination of strength and vulnerability that
exists in the work of Cole Porter.  She starts off slow and brooding, and as the song
progresses, she reaches a zenith of intense crescendo where she almost holds up her
strong vulnerability for all to see.  I think that it's important to really feel the
power of the words and there is a melancholy that she brings to it that I think Porter
would have appreciated.  While he was a showman, Cole Porter was an artist and
understood the value of melancholy on stage, and this version nails it.  When she starts
with the, "In love with the night mysterious/ the night when you first were there," it
really gets to you and takes you to a new understanding of the song.  I would examine as
many versions as you can and note what it is you like about them.  Yet, I would give
small diligence to the version by lang and see what you think.  In sampling these
versions, you will get a feel for what you can do with the song and what should be done
with it.
