“50 years ago, we introduced the world to ‘The Bologna Song’ as a way to spotlight our delicious deli meats and cement the brand’s legacy and mantra of uniting millions around a love of meat,” said Shelby Max, brand manager for Oscar Mayer, in a statement. “We knew this anniversary was a moment that needed to be celebrated in a big way.”

Oscar Mayer has not used the jingle in ads since 2005. Previous versions have included the bologna song being sung by children. A 1980 spot shows three blonde siblings sitting on a porch swing singing the song. The jingle was featured in a 1990s ad showing kids and parents singing the tune.
