93.6 Rock Radio based in Renfrewshire set up a guitar rack outside the station premises with a sign saying 'Free Air Guitar – please take one'.

Peter Border, 18, from Glasgow, who was outside the station, said: “It's a great joke! I even heard people were travelling from miles away to come and pick one up!”
