Larry Izzo's annual evening of karaoke to benefit the brave folks fighting in Iraq and Afghanistan was a raucous affair. The Pats linebacker, whose late father was a West Point grad, conceived of "Larryoke" after paying a visit to the troops in the Middle East. (Proceeds from last night's event at the Roxy will support several military charities, including the Massachusetts Soldiers Legacy Fund, the Pat Tillman Foundation, and the Intrepid Fallen Heroes Fund.) Izzo got the party started with "Born in the U.S.A.," and Lonie Paxton followed with "Rockstar" by Nickelback. Other Pats playing along included Benjamin Watson, Matt Cassel, Stephen Neal, Tom Brady (and girlfriend Gisele Bundchen), Wes Welker, who sang BTO's "Takin' Care of Business," rookie punter Mike Dragosavich, who wore a headband while warbling Olivia Newton-John's "Let's Get Physical," and Eric Alexander singing falsetto on Bell Biv DeVoe's "Poison." Lineman Dan Koppen crooned the "Cheers" theme, and discouraged potential groupies by flashing his new wedding band. All in all, a grand time.
