Saddened to find that the NYT's obituary for Tom Lehrer does not mention him granting permission to 2 Chainz to sample "The Old Dope Peddler":
"As sole copyright owner of 'The Old Dope Peddler', I grant you motherfuckers permission to do this. Please give my regards to Mr. Chainz, or may I call him 2?".
RIP to a master lyricist.
