Yoko Ono, director of this year's Meltdown Festival on the Southbank, kicks off the annual arts event herself today (14.06.13), with a rare appearance of the Plastic Ono Band.
Joining his mum in the Give Peace a Chance band is Sean Lennon, whose dad John is also at the festival in spirit in the form of the John Lennon Educational Tour Bus, in which young bands can learn how to make music videos. It's parked outside the Royal Festival Hall.
Other big names appearing at Meltdown 2013 include Boy George; Iggy Pop; Marianne Faithful; Peaches doing Peaches Christ Superstar; Siouxsie - once of Siouxsie and the Banshees and Patti Smith.
"I am deeply honoured to curate the world-famous Meltdown Festival," said Ono.
"Let the fun begin!"
Meltdown takes place at various venues on the Southbank from 14-23 June.
