Comedian Gallagher suffers heart attack at Texas club March 15, 2012 -- Updated 1836 GMT (0236 HKT) American comedian Gallagher is "slowly recovering" from a heart attack suffered just before he was to perform at a Texas club. The 65-year-old comic is listed in stable condition in a Texas hospital, his manager says Gallagher's shows are postponed through next week, she says "His family is with him," the manager says (CNN) -- The comic Gallagher, known for smashing watermelons, is "slowly recovering" from a heart attack suffered just before he was to perform at a Texas club, his promotional manager said Thursday. "We will not know the outcome until sometime tomorrow," said Christine Scherrer. Gallagher, 65, is listed in stable condition at an undisclosed Dallas-area hospital, Scherrer said. He was about to go on stage Wednesday at Hat Tricks, a Lewisville, Texas, club, when he fell ill and was taken to a hospital by paramedics, she said. "His family is with him and Hat Tricks has been unbelievable with the help and support with everything," Scherrer said. His shows in Texas, Oklahama and Oregon scheduled through next week have been postponed, she said. Craig Marquardo, who said he manages Gallagher's "bigger deals," said this is the comedian's third heart attack. "He's weak," Marquardo said. He's having difficulty. Scherrer, however, told CNN any information from Marquardo is "100 percent inaccurate," saying he is not Gallagher's manager. Gallagher's family is "fuming" over reports quoting Marquardo, she said.
