Some of these 'singalong' parlors still exist, faded and tired but otherwise unchanged, offering a taste of popular and cheap entertainment from a past era. How these survive in anyone's guess. The parlors usually have an organist (who can also play a guitar) and a handful of habitual customers who sing Cantonese songs...and occasionally Western oldies such as "Sealed With A Kiss" by the Canton Singing House organist.
I have found Alessandro Bergamini's China gallery to hit all the right notes in that regard. Most of his images were made in Guizhou; a province located in the southwestern part of the country, and well known for its traditional rural villages, inhabited by minority groups like the Miao and Dong. Other images in the gallery were made in Guangxi , another autonomous region bordering Vietnam, and home to the famous cormorant fishermen of Guilin. I haven't been but I read that even though the water is too polluted now for fishing to be sustainable, these fishermen are catnip for many photographers, and earn their living in that fashion.
The patrician-looking (and rather taciturn) sadhu in the top photograph did tell me that he had a family, had held a managerial position in the Indian Railway from which he earned a pension (now paid to his wife), but had decided to detach himself from temporal life and was currently studying the Vedas. These are the oldest scriptures of Hinduism. He was the embodiment of a real sadhu who had really espoused the Vairāgya, and was far different from the "sadhus" I encountered on the ghats of Varanasi (below) almost 8 years later.
