Red Red robin[charlton]Fields ofathenry[celtic], I had a wheel barrow, but the wheel fell off[ NottsCounty], this is an interesting one, apparently composed by someone in the stadium, when the wheelbarrow [that was used for carrying the meat pies]wheel fell off at a match.Iam forever blowing bubbles [west ham].
