tribute to Lennon, "All Those Years Ago". Bob Geldof said he wrote the 1984 Band Aid charity single "Do They Know It's Christmas?" out of a wish to create "something that could be sung all around the world, like 'All You Need Is Love'". He also credited the Beatles' Our World performance as part of his inspiration for staging Live Aid in 1985. At Live Aid on 13 July 1985, Elvis Costello performed "All You Need Is Love" before a television audience estimated at up to 1.9 billion. Costello introduced it as an "old Northern English folk song" and sang with a "vitriolic snarl", in Riley's description, that suggested "how far there still was to go rather than how far we'd come" in terms of realising the song's message. "All You Need Is Love" was part of Queen Elizabeth II's entrance music at the official millennium celebrations on 31 December 1999. The Beatles' recording was played just before the midnight festivities at the Millennium Dome in London. In 2002, the song was performed by choirs across Britain during the queen's Golden Jubilee celebrations. A cover version of the song was used in a 2007 advertisement for Procter & Gamble's Luvs baby product brand. In 2009, Global Beatles Day was founded as an international celebration of the Beatles' music and social message. The event takes place on 25 June each year in memory of the Our World performance of the song. In October 2021, American singer Katy Perry released a cover of "All You Need Is Love" for a Gap holiday advertisement.
