The hook is a sample of "Bobby Sox Idol," a song recorded by calypso singer Wilmoth Houdini in 1947. There's also an interlude containing "My Favorite Things
" from Rodgers and Hammerstein's The Sound Of Music
The Avalanches' Tony Di Blasi told ABC the "Favourite Things"' sample is his favorite part of the song, "because growing up with five brothers and sisters we used to all watch musicals and The Sound of Music
was one of the favourites. We were like little Von Trapp family singers ourselves."
