After 50 years as a television host, Regis Philbin has retired, making his final appearance on Live! With Regis and Kelly this morning. Naturally, the event was “star-studded,” with a celeb-filled audience (Tony Danza! Donald Trump!) and a montage of notables doing their best Reeg. Mayor Bloomberg even stopped by to give Regis a key to the city. Before his brief, final words, Regis was treated to a musical tribute à la Rent’s “Seasons of Love” with lyrics re-written just for the host: “995,600 minutes. How do you measure, measure a career?” (These Regis-ized songs have been happening all week.) Oh, and 995,600 minutes is nearly two straight years of host chat, if you’re keeping score at home. Watch for yourself in our clip.
