The Reunion Tour
Frank Sinatra, Dean Martin, and Sammy Davis Jr. tried to reunite in 1988 for a tour. Apparently, the fault of the failed tour leans on Dean Martin who showed no interest in partaking. He would mumble through lines, forgetting lyrics, and ended up getting hostile. The tour ended after six nights.
Bloody Mary Nightmare
Obviously, these guys were known for partying. They were consistently at Vegas hotels and bars. One night, a hotel reported that they had ordered 300 Bloody Mary's to their rooms over the course of a single night.
