Hi, It's difficult to hear over the bus sounds, and I cannot identify the song however I have a couple of suggestions. First, it may be that it isn't so much a song as it is a sound track segment written by a composer for the background of the film. Find out the name of the film.. it looks like a documentary put on by public television. Find out who produced the film. Then email the producer or the company which made it, or the station that broadcast it to get the producers number. Then you can email or call and ask about the music behind the particular segment.. who wrote it... what it is, etc. It may or may not be available, but if it was specifically written for the film, you may be able to find the composers name and see if anything is available by that composer, or write to them and ask for the music or piano soundtrack..mention the segment it's in.... they may be willing to send it or sell it to you, or let you know where you can get it. If you have the film or access to it, the composer and/or name of the piece should appear on the credits somewhere at the end of it.
