Rock musician Vince Neil will appear in the season finale of \"Ghost Adventures,\" which was taped at a Las Vegas hotel, Travel Channel said Wednesday. The April 27 season capper will feature appearances by Frank Sinatra\'s former pianist, Bruce Westcott, and Jamie Gold, the 2006 World Series of Poker champion. They will join the show\'s team of paranormal investigators -- Zak Bagans, Nick Groff and Aaron Goodwin -- to check out The Riviera Hotel, which some say is haunted. \"Built in 1955, it\'s one of the oldest hotel and casinos still standing on the Vegas strip,\" a synopsis of the show said. \"Filled with history, the hotel has had a roster of celebrity clientele and was formerly connected to the Chicago Mafia -- needless to say, the hotel has had its share of good times and bad. Perhaps its most well-known guest was Frank Sinatra, who had his own penthouse suite where he often threw lavish parties. As the \'Ghost Adventures\' team heads into the hotel to begin their investigation, they enlist the help of a few special guest investigators including: Vince Neil, leader singer for the rock band Motley Crue; Bruce Westcott, Frank Sinatra\'s former pianist; and Jamie Gold, 2006\'s World Series of Poker champion. Together the group -- along with Vince\'s entourage -- explores paranormal occurrences in Sinatra\'s room and various guest rooms. Attempting to channel Sinatra, they recreate a party in his suite, which delivers some startling results. As Vince and his entourage experience unexplained first-hand encounters -- including scratch marks on one woman\'s back, cold sensations, voices and knocking -- Zak, Nick and Aaron document the multiple EVPs and unexplained events. But it\'s not until Vince and his girlfriend, Rain, head into room No. 908 that Vince encounters an overwhelming physical experience.\"
