Chase Again (一追再追) is the theme song to “The Revertible End” (本可改變的結局). The song is written by Dick Lee and Lin Xi (林夕) who spent over 1 year time in its planning and creating, completing it in 2013. It is performed by Sammi Cheng (鄭秀文). “Chase Again” was written as a sequel to Leslie Cheung’s (张国荣) “Chase” (追), the theme song to “He’s a woman, She’s a Man” (金枝玉葉), written in 1993 by Dick Lee and Lin Xin. The music video also pays homage to Leslie, as it was shot just outside Central District’s Mandarin Oriental, the very hotel where Leslie had taken his life. Sammi, like Leslie, suffered from depression in the past and has a very personal connection to the song. During a press interview, she stated that she did the song for FamilyLink, that she too suffered from depression for over three years. Because of this, she feels greater emotions when performing “Chase Again”. She also stated that though the song is a sequel to Leslie’s “Chase”. The only thing she wishes is to bring hope to those affected by the disease.
