Pop Pop Music is presenting “Canto-Jazz Extravaganza: Hong Kong TVB Theme Songs Revival” this weekend, and Lim Soon Heng attended a rehearsal and watched the dancers choreograph their moves around the veteran singer Evon Low. The rehearsed dances suggest that the show will take its audience back in time to the glitz-and-glamour days of the chanteuse with her bevy of followers in tow.
