Bobby Munson had an interesting side job when he wasn’t breaking the law or riding a bike: he was an Elvis impersonator. Bobby explains on the show that he’s doing the gig for extra money, and we actually see the man at work in the pilot. He has to miss some club business because he’s booked several shows, but when he arrives at the venue, he finds he’s been replaced by “Asian Elvis,” someone who club owners say will cater to Korean tourists in town.
This won’t stand for Bobby Elvis, so Half-Sack (Johnny Lewis) beats up the Asian Elvis, and the episode ends with Bobby singing “Only Fools Rush In.” We saw less and less of Bobby Elvis over the years. Even before the series finale, Kurt Sutter was asked by fans about a return from Bobby’s performances. At Comic Con 2014, Sutter told polling fans that Bobby was just too busy with the club drama to channel the king before the show ended (via Entertainment Weekly).
It wasn’t the only storyline that seemed to be pushed aside as the show progressed, either. There was also Unsers (Dayton Callie) once seemingly terminal cancer that ultimately didn’t end the way fans expected based on how the storyline was first laid out on Sons of Anarchy.
