Fans of John Lennon joined Yoko Ono in Iceland

Ono lit up the Imagine Peace Tower in Videy island, near Reykjavik, as a choir sang Lennon's 1975 song Imagine.

She was accompanied by her son Sean Lennon, Beatles drummer Ringo Starr and George Harrison's widow Olivia.

"We're all here for Johnny's birthday and the big light," Starr said. "I love the light."

The tower is a beam of light radiating from a wishing well, which is engraved with the words "imagine peace" in 24 languages.
