Question: Question: How old was Lombardo when he first moved to CBS television? Passage:National media coverage has historically been centred upon New York City and Times Square. Bandleader Guy Lombardo was well known for his live broadcasts from New York with his band, The Royal Canadians—whose signature performance of "Auld Lang Syne" at midnight helped make the standard synonymous with the holiday. Beginning on radio in 1929, Lombardo moved to CBS television from 1956 to 1976, adding coverage of the ball drop. Following Lombardo's death, Dick Clark's contemporary competitor, New Year's Rockin' Eve (which premiered for 1973 on NBC, and moved to ABC for 1975) became the dominant New Year's Eve special on U.S. television (especially among younger viewers), with Clark having anchored New Year's coverage (including New Year's Rockin' Eve and the one-off ABC 2000 Today) for 33 straight years. After suffering a stroke in December 2004, Clark missed the 2005 edition with Regis Philbin filling in for him, and he retired as full-time host in favor of Ryan Seacrest for 2006 due to a lingering speech impediment. Clark continued making limited appearances on the special until his death in 2012.
