Rong Kham Kamphaeng, translated as Sing Across the Wall, premiered in Thailand in 2020 on Workpoint TV and became one of the channel's popular music entertainment shows. In each episode a celebrity performs a duet with a hidden singer separated by a wall, then tries to guess that person's identity before the reveal. Clips and audio cues from the programme circulated widely on Thai social media and video platforms, where fans reused its dramatic reveal moments for edits, parodies and guessing games long after broadcast.
