LOL! You mean Don Fagen's "I.G.Y."? Great tune -- in fact, I'm gonna listen to it now.
There is the possibility the song referenced is either Sam Cooke’s “What a Wonderful World This Would Be” or Louis “Satchmo” Armstrong’s “What a Wonderful World”.
The main chorus of “I.G.Y.” starts with “What a beautiful world this could be. What a glorious time to be free”.
