Best soul duo ever. And half way into their career they hated each other.
Separate dressing rooms. Only got together on stage...
Apparently got into a fight once where Dave pulled a knife on Sam.

"Conflict between Moore and Prater
Sam & Dave were known for having a very tumultuous partnership during most of their 21 years together. According to Moore, they did not speak to each other offstage for almost 13 years. During the 1970s, they broke up many times, and typically would show up separately for shows, require separate dressing rooms, not look at each other onstage, and communicate through intermediaries. They also had performances in the 1970s where only one of them would show up, leading to the eventual departure of Moore, and the continuation of the name "Sam & Dave" by Prater pairing with vocalist Sam Daniels. Moore describes personal issues with Prater, drug use, touring fatigue, and a desire to do his own act with new material as contributing to their break-up and replacement of Dave. Prater attributed their rift and break-ups to Moore's frustrations in wanting to do his own act and diversify from repeatedly performing the Sam & Dave song catalog (which Prater has said that Moore didn't like very much)."
