10477 Lacumparsita           Discovered 1981 Mar. 2 by S. J. Bus at Siding Spring.
La Cumparsita is a song considered the `anthem of the tangos' created and written by the Uruguayan composer Gerardo Matos Rodríguez (1897-1948). It was played for the first time in 1917 in Montevideo, site of the 2017 Asteroids Comets Meteors conference.
