Yes, I e-mailed it to Rush and to his parodist, Paul Shanklin, at the same time on Saturday I posted it here. Haven't heard anything back yet.
BTW, back last November, I e-mailed Rush and Paul another song I wrote, "The Palm Beach Pokey," also on the same day I wrote it. I didn't hear back from them, but I did find out later that Rush either referred to the song or read it on his show at some point.
