One of the midrashic significations of God's final allembracing assessment of this creation, "that it was very good" (tov meod
), is a contrastive one--this world is good as opposed to all the other worlds which were created and destroyed.

Glantz, a Chasidic/rock/world-beat singer and musician, with bushy black beard, long twirly sidelocks, and a powerful stage presence, joined forces with Gidi Gov, the quintessential secular sabra singer, to sing `Kol Ha-Olam Kulo, Gesher Tzar Meod
.' (The whole world is a very narrow bridge.) The chorus, belted out by the two performers on stage, as well as everyone in the packed auditorium, is: "But the main thing above all, is not to be afraid at all."
Division G saw the UFO 34 Spider, skippered by Mick Austin, gain a vital three place margin in the final race to overtake series leader Allo Allo (Claire Meod
) and win the series by two points.
