On November 13, he joined the American recording artist Madonna on stage during her concert at Madison Square Garden in New York City and they performed a mashup of the song and her 2008 hit "Give It 2 Me." Psy later told reporters that his gig with Madonna had "topped his list of accomplishments." On November 18, Psy, who rocked out in traditional Hammer pants, closed out the 40th American Music Awards show with a performance of "Gangnam Style" joined by surprise guest MC Hammer, who brought in his own moves and Psy's horse-riding dance as the song mashed into his 1990s hit "2 Legit 2 Quit." Jason Lipshutz of "Billboard" commented that "Psy's feverish rendition of 'Gangnam Style' accomplished what so few award show performances can: a palpable sense of excitement. The combination of the K-pop star and MC Hammer ... was a stroke of genius that very few could have seen coming," and chose it as the best performance of the night. "The Tonight Show with Jay Leno" did a special Thanksgiving broadcast with an all-military audience on November 22, and Psy dropped by as the musical guest. The singer sang the song and danced alongside the soldiers, going into the crowd for part of his performance.
