Turns out, it was just a rehearsal. On Wednesday, the three-time Grammy winner surprised concertgoers at London's Eventim Apollo with a performance of the 1997 hit alongside Imbruglia herself! "Such an honor to sing with the insanely talented, insanely kind Natalie Imbruglia," Rodrigo, 19, wrote on her Instagram Stories, captioning a backstage photo of the two. "What a dream." She also shared a video of her and Imbruglia, 47, singing the song. "I think she's the most fantastic artist, the most fantastic singer," Rodrigo said when introducing Imbruglia to the audience. Just days earlier, on Sunday, Rodrigo was videoed singing "Torn" at Bunny Jackson's Dive Bar in Manchester, England, where the drinking age is 18. Imbruglia's version of "Torn" is itself a cover, with three other versions of the tune released before the Australian singer dropped it as the first single off her debut album. It was first recorded in 1993 by Danish singer Lis Sørensen, before Los Angeles rock band Ednaswap —whose members Scott Cutler and Anne Preven wrote the song, alongside Phil Thornalley — came out with their own version. American-Norwegian singer Trine Rein released a recording of the song in 1996. Imbruglia's cover has become the most popular, however. Her version sold more than four million copies worldwide, peaking at No.1 on the Hot 100 Airplay for 11 weeks in a row.
