Some of the biggest stars in music have taken to the stage for the first of two Children In Need Rocks concerts.
Among the acts joining organiser Gary Barlow on stage was former Abba star Agnetha Faltskog, performing in front of a live audience for the first time in 25 years.
It is the first time the pair have performed their duet, I Should've Followed You Home, together - as they originally recorded their parts of the song separately.
Little Mix, Dizzee Rascal, Barry Manilow, Nicole Scherzinger, Kings of Leon and Barlow's former Take That band mate Robbie Williams were also among those who performed at London's Hammersmith Apollo.
