More Japanese oldies on Youtube:
This 1963 Japanese song,Washington Park, I always thought had a catchy melody.
I was never sure whether it was a Japanese original, or if it was a cover of something else, until I heard a hip-hop version of it recently in a bar.  So I decided to search the Internet.
It turns out the song was originally recorded as an instrumental song back in America.
But it was funked up a little bit by James Last in this version here.
And that version in turn was sampled for this hip-hop song by French hip hop group Chinese Man.
It's a repetitive musical hook, I know, but I like it.  I think it works quite well as hip-hop.
