Your Song

Froggie has been listing to the radio and heard a good tune. Froggie doesn't know what the song was called, but he remembered a part of the song. Maybe you can help him out?
Ah zutto issho ni itakatta no ni oiteikanaide Ah - eien nante saisho kara nakatta ndane Ah kowakunaru - yo kotae no nai michi hitasura aruku Ah shinken ni - koi wo shitetanda
