Owen Cheung (張振朗) expressed he would be singing Nicholas Tse’s (謝霆鋒) song (愛後餘生) when recording the show, Cantopop At 50 (流行經典50年) on 26th July 2019: “I am a super fan of Nicholas and disguised as him before, but I am not doing it tonight. (Did you see him personally before?) Nope. I wanted to watch his concert earlier but too busy. My brother and his wife watched his concert and everyone was very excited once Nicholas started to sing. He joins the show business at a young age and is considered a superstar during my secondary school days. (Become an actor because of him?) I learn guitar because of him though. (Not singing the song (活著Viva)?) I am clueless and did learn it but not very good. (Upgrading yourself?) Please do not force me.”

When asked if he wished to sing theme songs for the drama, Owen confessed his desire and said: “In fact, the theme song for The Offliners (堅離地愛堅離地) series sang by me is my first time and hopefully everyone will get a chance to listen to it. (Wanted to be a singer?) Used to in the past but I fail to and become an actor instead, since I love acting as well.”
