Bruce Springsteen and the E Street Band will make a musical sandwich with Paul McCartney tomorrow night at the 12-12-12 Concert at Madison Square Garden. The scrumptious filling will be composed of the Rolling Stones, The Who, Billy Joel, Bon Jovi and several more star acts. The show begins at 7:30 pm, streamed on dozens of websites and broadcast everywhere on TV. It’s also being shown in movie theaters. Check www.121212.concert.org for all the details. Organizers say that between ticket sales at the Garden (very expensive) and sponsorships they’ve got $30 million in hand. Devastated areas in New York and New Jersey really need it as people are suffering without their homes or possessions. PS I’d bet good money now that the closing song is “Hey Jude.” The opener? I’m still waiting for Bruce to do “Sandy (Fourth of July).” Tickets are still available, in short supply and high prices, at StubHub.
