( CNN ) -- Country music artist John Rich had such a great time in Las Vegas that he was not fit to fly home to Nashville on Sunday , according to Southwest Airlines . Rich , 37 , was escorted off a Southwest flight before it took off from Las Vegas Sunday night , airline spokeswoman Christi McNeill said Monday . `` Our crew assessed the situation and determined that the passenger was not fit for travel , '' McNeill said . It was not clear what led to Rich 's getting booted from the plane , but the singer 's spokeswoman Tree Paine denied online reports that he was involved in a fight with another passenger . `` Did John Rich have a great time with his fans in Vegas ? Yes . Was there an altercation ? Absolutely not , '' a statement said . Southwest gave Rich -- of the band Big & Rich -- and a fellow traveler a refund and they found alternative travel arrangements to Nashville , the airline spokeswoman said . `` Our employees are responsible for the safety and comfort of everyone on board a flight , '' McNeill said . `` If we can mitigate an uncomfortable situation prior to departure , it is our preference to do so , and that is what happened in this scenario .
