The Pokemon Company uploaded a nostalgic video on Youtube and Facebook to celebrate the release of Pokémon: Let’s Go! Pikachu/Eevee featuring the “Pokémon Theme” song aka “Gotta Catch ‘Em All” song from the franchise’s anime series’ first season of the western adaptation.

The song has been synonymous with the Pokémon franchise ever since its premiere in the debut episode “Pokémon, I Choose You!” in September 8, 1998. The “Pokémon Theme” song was written by John Siegler and John Loeffler and performed by Jason Paige.

Watch the short video below and sing along if you know the words (who doesn’t?!):
