On the two recent occasions I was in Shanghai, I was thrilled by the abundance of candid street photography opportunities that presented themselves in its old neighborhoods. The narrow lanes crisscrossing these neighborhoods are called lòngtáng (弄堂) or alternatively, lilong (里弄), where whole communities live and sometimes work. The Shanghai lòngtáng can either refer to the lanes that its houses face onto, or to a group of houses connected by them.
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.
