Todd Rundgren's Utopia and Hot Tuna performed at the Knebworth Festival in Hertfordshire, England, before approximately 200,000 fans. Tickets cost £4.50. The concert was falsely promoted as “the last Stones concert ever to take place in Britain” in order to boost ticket sales. RCA also announced that sales of
Elvis Presley's recordings had exceeded 400 million units; later estimates by Graceland and Sony put his worldwide sales at more than one billion recordings.
