An Indian man missing for 40 years was to be reunited with his family on Thursday after a YouTube video of him singing a popular Hindi film song went viral. Khomdram Gambhir Singh was 26 when in 1978 he left his home in Imphal, in the remote northeastern state of Manipur, and never returned, according to reports. For four decades his family heard nothing.Then a clip showing a grey-bearded man singing a Bollywood song on a Mumbai street 3,300 kms (2,000 miles) away appeared online. In it the singer identifies himself as Khomdram Singh of Manipur. A viewer brought the video to the attention of a local association in Imphal who informed Gambhir’s family. (AFP)
