Pokémon Theme

"Pokémon Theme" (also known as "Gotta catch ’em all!") is a song written by John Siegler and John Loeffler and performed by Jason Paige. It is the original theme song for the first season of the English adaptation of the Pokémon anime. Since its release, the song has been virtually synonymous with the Pokémon franchise because the line "Gotta catch ’em all!" has become its official English slogan; it is derived from the Japanese ポケモンGETだぜ! ("Pokemon [getto] da ze!").

"Pokémon Theme" is a fast-paced pop rock song in the key of G Minor, with continuous male vocals intermixed with a backup vocal accompaniment.
