During Harry Styles' concert tour, fans are unexpectedly singing lyrics from Australian band 5 Seconds of Summer's song "Telephone Busy" during a break in Styles' performance of "Ready, Steady, Go." This trend began with a TikTok remix posted by @millsberry75 in March and gained momentum when 5SOS incorporated it into their set at Lollapalooza. The phenomenon reflects the historical connection between One Direction, where Styles was formerly part of, and 5SOS as an opening act for One Direction tours years ago. Fans celebrate this organic trend that originated from social media and has now become a regular occurrence in concert venues like Madison Square Garden during Styles' residency there.
