PEOPLE: According to a News Corporation (which owns Fox News) wire report, the Rocket Man, 63, serenaded the 400 guests into the wee hours Saturday night to celebrate the marriage of Limbaugh, 59, to Kathryn Rogers, 33, in the Ponce de Leon ballroom of Florida’s fabled Breakers hotel in Palm Beach. Sir Elton’s fee: $1 million, the report notes. Amid dozens of giant bouquets of white roses (and very tight security), reports the Palm Beach Post, guests at the wedding included former Bush adviser Karl Rove; actor-politician Fred Thompson; former Kansas City Royals slugger George Brett; Fox News commentator Sean Hannity; former New York City Mayor Rudolph Giuliani; New England Patriots owner Bob Kraft; former Clinton adviser James Carville and his wife, GOP analyst Mary Matalin; and golfer Tom Watson. A wedding guest also tells PEOPLE that among the others was Supreme Court Justice Clarence Thomas. MORE
