Šaban Bajramović “The King of Gypsy Music”, wrote the song Opa Čupa in 1977. This YouTube also gives a brief biography of the man. He’s singing the official Roma anthem Djelem Djelem (which he did NOT write: everything else on the screen titles agrees with what is written elsewhere).

Andy Bettis from the UK is credited with choreographing a dance to the song. Steve Kotansky brought it to the USA.

Some IFD groups prefer to dance to the music of Brass Menažeri, from Oakland CA.
