For example, Lansbury sang it at the 2002 Christmas concert with Mormon Tabernacle Choir. Similarly, Dion and Bryson duetted at the JT Super Producers 94 tribute concert to David Foster, and as part of Dion's 1994-95 The Colour of My Love Tour, though they have also often sung with different duet partners. Dion has sung with Tommy Körberg, Brian McKnight, Terry Bradford, Maurice Davis, Barnev Valsaint, and René Froger among others; Peabo has sung with Coko and Regine Velasquez.
