I also had an inkling that it may be a Les Miz reference as there isnt a person I know of who DOESN'T like it. I, in fact, love it. However, to answer your question, yes there is a poem that uses the name and is quite good. Now, for the life of me, I cant remember its title so I am afraid I am going to be no help in enlightening you as to where to find it. All I know is that I once read it, and loved it myself.
In regards to Mamma Mia, I saw it in Toronto and really enjoyed it. Not a favorite of mine, but it was excellent. I actually wasnt sure if I would like it or not because I am not an ABBA fan, but to my surprise, I enjoyed it immensely and will recommend it to anyone interested.
