'PEnnsylvania 6-5000' (736-5000) is the historic phone number of the Pennsylvania Hotel in New York, claimed to have been in use for nearly a century - the full number is now +1 (212) 736-5000.
"Many big band names played in the Hotel Pennsylvania's Cafe Rouge Ballroom, including the Glenn Miller Orchestra; the phone number became the inspiration for the Glenn Miller 1940 Top 5 Billboard hit song of the same name, written by Jerry Gray and Carl Sigman."
