Manning's annual birthday celebrations attracted dancers and instructors from all over the world. His 80th birthday, in 1994, was commemorated by a weekend-long celebration in New York City; his 85th culminated in a sold-out party at New York's Roseland Ballroom, where a pair of his dance shoes were placed in a showcase along with those of dancers such as Fred Astaire. Dedicated cruises were organized for his 89th and 90th birthdays; for his birthday dances, Manning followed his custom of dancing with one woman for every year of his life. He continued this custom through his 94th birthday.
