I kind of am, and I will check out your links.
I'm particularly intrigued by the notion of "hidden rhymes" that aren't apparent to a casual listener, like the ones Sondheim famously discussed in "The Ladies Who Lunch" (laugh/caftans, gas/classes, etc.). I've noticed a similar one in "Unworthy of Your Love," viz. sky and I in the first verse:
I am nothing
You are wind and water and sky
Jodie
Tell me, Jodie, how I can earn your love
(Similarly with god/body in the second verse.)
Does anyone know of other "hidden rhyme" examples, from Sondheim or otherwise?
