Protest at Radio City Music Hall show in New York

http://jewssansfrontieres.blogspot.com/2009/05/new-york-activists-to-singer-leonard.html

Protestors chanted “Leonard, Leonard Have A Heart, Don’t Help Apartheid With Your Art” and sang “Ain’t Gonna Let Occupation Turn Me Round, Gonna Keep On Walkin’, Keep Boycottin’” to the tune of “Ain’t Gonna Let Nobody Turn Me Round”. A particular crowd favorite was, to the tune of Frere Jacques,

Are you sleeping, Are you sleeping,

Leonard Cohen, Leonard Cohen

While your songs are so fine

Israel’s taking Palestine

Don’t go there, Don’t go there

Here's a photo from the protest, or at least some graffiti.
