Pairs on the dancefloor for a Gay Gordon？？
The song ended and, instead of the thumping bass of another pop song, it was the screech of fiddles and an accordion that pierced the sudden quiet.
“All right!” Mrs Peters, the head of PE, clambered up onto the stage, microphone in hand. “Pairs on the dancefloor for a Gay Gordon!”

I would like to know what dos "Gay Gordon" here mean ? Is it a name of a singer ? Thanks.

Thank you very much.

Answer

It's the name of a common Scottish folk dance. "pas de bas" is a step in a dance though I am not sure exactly what kind of step.
