The Wonder Girls had their official comeback on the weekend of September 26–28, 2008, performing on KBS's "Music Bank", MBC's "Music Core", and SBS's "인기가요" ("Top Songs"). At the end of October, the group briefly used the "Rainstone Remix" of the song. On 8 August 2015, they reprised this song with instrumental version in conjunction with their 2015 comeback as a 4 members band group at You Hee-yeol's Sketchbook.
