The problem is Jabba is meant to be the Star Wars version of the sort of character Frank Thring and Charles Laughton once cornered (Scheherazadian debanched obese royal grotesques) crossed with the sort of mafioso that Brando's Corleone was a caricature of.

The funk, disco dance routine just doesn't fit into that environment which is why I suggested the exaggerated alien burlesque dance some pages back (pg 87 to be precise).

If you replace the song and have the band as a backing for exotic dancers (like Oola) it fits better in the scene than a sudden reminder of 1983 (with funky puppets) or 1997 (with CGI cartoon characters).

The music should do for belly dancing what the Cantina group did for the Tommy Dorsey sound.
