Shortly after appearing on "American Idol", Day returned to performing on cruise ships. Between 2005 and 2006, it was reported that he had been performing on two different ships operated by Royal Caribbean – "Voyager of the Seas" and "Explorer of the Seas". By 2011, Day had established a musical act performing on Holland America's MS "Veendam". Day has also performed in Las Vegas and been cast in several low-profile theatrical productions. It has been suggested by PopCrush, that Day may have continued performing for Muhammad Ali, extending his purported pre-"Idol" history with the iconic boxer.
