Everyone is fighting to find a cure for cancer, but the wannabe boxers who stepped into the ring this week at Boston’s House of Blues are actually fighting. Thirty men and women traded jabs and uppercuts at Haymakers for Hope, a hard-hitting fund-raiser for the Dana Farber Cancer Institute and the Jimmy Fund. Cofounded by Julie Anne Kelly and Andrew Myerson, the charity boxing tournament put the aspiring pugilists into the ring after giving them four free months of training. (None had previous fighting experience.) The event, emceed by Jam’n 94.5’s Ramiro Torres, raised over $200,000.
