Yoko Ono will be on the island of Viðey in Reykjavík, Iceland later today (Thursday) to relight the Imagine Peace Tower on what would have been John Lennon’s of his 74th birthday.

On her Facebook page, she invites fans to tweet messages to @IPTower or email wish@IMAGINEPEACETOWER.com.

Yoko adds that the Tower is meant to “give light to the strong wishes of World Peace from all corners of the planet — and offer encouragement, inspiration and a sense of solidarity in a world now filled with fear and confusion. Let us come together to realize a peaceful world.”

There will daily live online coverage from tonight through December 8th (the anniversary of John’s death) at ImaginePeaceTower.com at 4 p.m. ET/ 1 p.m. PT.
