鄭中基昨（13）在香港紅館開唱，他已經好幾次新年舉辦演唱會，自己都忍不住說：「這次是我第三次農曆新年在紅館開唱，上一次是2019年，而我這輩子都只有在紅館開過4次演唱會，真是十分之匪夷所思呀！」
演唱會以「搬屋」、「想愛你」、「黑色風暴」和「天意」開場，鄭中基也帶來練習多時的烏克麗麗，以「Some where over the rainbow」及「What a wonderful world」送給歌迷，他也用吉他自彈自唱「晴天陰天雨天」、「救救我」、「我代你哭」。
首場演出嘉賓是呂爵安「阿仔」Edan，唱「有種」2人一起向觀眾拜年討紅包，現場氣氛十分高漲，鄭中基說：「討回來的回包會全數捐出去。」然後Edan還送了一份「厚」禮給他，2人在電影「闔家辣」飾演父子，Edan說：「我同『老豆』是因為拍『闔家辣』認識，當時他的角色是負責切辣椒，所以我想送對『厚』手套給他。」說完2人各戴一個手套合唱「傷心的小鸚鵡」，引得觀眾大笑。
演唱會尾聲，全場觀眾一同合唱「無賴」，鄭中基相當感動。完場後歌迷仍然不肯離場，更點起歌來，一向寵粉的鄭中基當然會滿足大家，再度唱出多首歌曲包括「青春痘」、「三生有幸」。鄭中基下月將來台開唱。 鄭中基下月將來台開唱。圖／機動娛樂提供
