Perhaps this is a song written by Uncle Walter's son. I'm thinking of "Waltzing with Bears" which is in the Digitrad. Walter is taken in the last verse.

Well we begged and we pleaded, "Oh please won't you stay" Managed to keep him at home for a day But the bears all barged in and they took him away Now he's dancing with pandas, And he can't understand us And the bears all demand at least one waltz a day
