Albert Richardson (1905-1976) of Burwash (best known for his rendition of 'the Old Sow') had Shenandoah in his repertoire. Probably learnt when he was in the Rover Scouts in 1928 - unless there is a latent Sussex singing tradition with it in I don't know about. Richardson also sung 'the Punch Bowl' - is this 'Fathom the Bowl', or is there something else with this as the title?
