The U2 frontman Bono described Jerusalem as a "great city" in a note left at his hotel after a visit to Israel earlier this month.
The Irish singer was spotted at a Jaffa restaurant last week, but was in the country on a private visit and did not perform.
However, he did leave an artistic legacy, writing a short poem in the guest book of the historic King David Hotel in Jerusalem.
The poem, published on gossip website Buzz Feed, noted that "in Jerusalem, hope springs eternal".
