JG Jam - SMILE - 6th July 2013
The performers are Club 2Gethr, Chris Woods, Aaron Douglas and Hamer and Isaacs Gypsy Swing Band.
None of them had met before appearing on JG's Saturday Show on 6th July 2013. They all performed individually before collaborating on the end of show jam.
With just 30 minutes rehearsal, they came up with this.
