The A.C. Walden Medicine Show was the name of a troupe of travelling musicians which performed at venues around the Federation through much of the 24th century. The Medicine Show, as it was informally known, began performing sometime prior to 2316. Among the members at that time were Kojo Pran, Tolik of Vulcan and his mate. Their daughter, T'Nallis, served as sound engineer. In 2316 Pran and T'Nallis had a son, Sonek Pran, and he also became a member of the troupe until leaving to attend YloTrap and pursue an academic career.
