Money (That's What I Want)
In 2011, McCoy and Mars performed "Billionaire" on their European co-headlining tour; McCoy sang it during his headlining leg in North America. That same year, it was also sung during the Vans Warped Tour, where McCoy's band, Gym Class Heroes, were the headline act. During Mars' debut international tour (2010–12) and the Hooligans in Wondaland Tour (2011), he performed a rock cover of "Money (That's What I Want)" (1959) by Barrett Strong. This served as an interlude before "Billionaire". On Mars' second world tour, the The Moonshine Jungle Tour (2013–14), he sung a cover of "Money (That's What I Want)" with "Billionaire" and Aloe Blacc's "I Need a Dollar" (2010). "Billionaire" was used as the introduction to Mars' performance on the Super Bowl XLVIII halftime show in 2014, sung by a children's choir. It was included on several shows of the South American leg during Mars' third world tour, the 24K Magic World Tour (2017–2018).
