been performing the now famous song, "永遠永遠" for three years as a part of their lineup in the pubs, as it had been given to them by the song's lyricist, 吳梵, who was a good friend of Yang's, but when renowned Taiwanese singer, Yi Jun Li 李翊君's manager, heard the band perform the song and realized the song's potential was being squandered in a pub atmosphere, requested the band give up the song to her.
