Does anyone know how the rikishi is chosen to do the daily closing ceremony? Is there particular meaning to the motions? I always find it interesting to watch, especially to listen to the crowd cheer as one foot comes down. On a separate topic, does anyone have a list of the former rikishi that participate in the song that follows the closing ceremony on the live feed? I have a partial list, and being new to sumo, it is hard to understand some of the history of who is who. Thanks in advance to anyone who might satisfy my curiosity.
