<human>: Give me a shortened version of the text

Just saw the Dropkick Murphys at Mohegan Sun (Casino in CT). During the second song I could see security jump to the very front by the stage. Best thing I know the lead singer is making the "cut it" motion slashing across his neck. The band stopped playing and he asked everyone to move back in the floor area to give some room. He kept checking in on the guy who was apparently having heart problems while repeatedly asking the crowd to back it up. 

While the medics were working to get him out a guy started fighting on the floor area and the lead singer, again showing how classy he was, told him to knock it off. The situation was over and they even made it a point to announce the sick persons name a few songs later and let us know he was ok.
<bot>: Dropkick Murphys fan goes down with heart trouble, they stop playing and get the crowd to clear out and told us later he was ok.
