U2 club show in Boston?

U2 is pulling out all the stops to hype its new CD, "No Line on the Horizon," which hits stores Tuesday. Bono and the boys played a surprise gig Friday on top of the BBC building in London, and Monday the lads take up residence on "The Late Show with David Letterman," where they'll be Dave's musical guest all week. (It's the first time a band has been given five nights on Letterman's show.) That's not all. According to the Hartford's Courant Eric Danton, the guerilla marketing campaign continues Friday, when Bono, The Edge, Adam Clayton, and Larry Mullen Jr. play what was supposed to be a "secret show" on the steps of Keating Hall at Fordham University. (Profs have been asked to cancel all their classes, but not told why.) So what, you say? Well, it's very hush-hush, but we hear that the Irish icons are looking to play a similarly stealth club show in Boston. Live Nation is emphatically denying it, but word is the mega-selling band, which had no difficulty selling out seven shows at the former FleetCenter in 2005, may return to its roots with a show March 11 at the Paradise. Why not the more spacious House of Blues? U2 is nothing if not nostalgic, and the band played its first headlining show in Boston at the Paradise in 1981. (For what it's worth, the Wailers are booked to play the Paradise March 11.) Of course, this would not be the band's only New England show promoting its 12th album. They're expected to play at Gillette Stadium in September.
