"[3][4] King was inspired by a performance he saw in 1918 of Ringling Brothers Circus, where he witnessed a man ride a unicycle on a highwire.
Irvin Feld, at the time the producer for the circus, saw the Troupe perform on The Tonight Show with Johnny Carson.
In 1981, the Troupe performed with the magicians Siegfried and Roy in their show "Beyond Belief" at The Frontier hotel in Las Vegas.
[10][11] Siegfried and Roy included the Troupe in a number where they escorted a white showgirl down a large staircase, an act that faced "extreme disapproval" from hotel bosses.
[11] Siegfried and Roy said[11] For us the King Charles Troupe was more than just a transitional act; we felt they gave our show more body and created an interesting contrast with what we were doing.
The street name sign is called "King Charles Unicycle Troupe Way" and sits on the corner of E. 170th St. and Clinton Ave in the Bronx, NY.
