LONDON'S NEW YEAR'S DAY PARADE, now in its fifth decade, is a cherished turn-of-year tradition bringing good old-fashioned fun to the U.K. capital. The event, which paused "marching time" during the pandemic, returns to its iconic parade route through the ancient City of Westminster. Cultural and community groups rub shoulders with leading professional entertainers and the mayors of London. Plus, more than 20 U.S. marching bands and 1,000 varsity cheerleaders, many of whom have been waiting in the wings for several years, are finally allowed to travel to London for their moment in the global spotlight.
