Get the Tissues Out
In an interview in last week's Onion A.V. Club, comedian Rob Corddry mentioned a little known "song" called "Nancy Grows Up" by '50s performance artist Tony Schwartz. Schwartz recorded his daughter from birth to her teenage years and spliced it all into a two minute file that is really moving. You can hear the file here, or click here for a more web-friendly version.
And thanks to Recidivism for posting the file.
