Madam, – Is it too much to ask to be able to travel on a bus in peace and quiet without being subjected to a man murdering a song as if accompanied by a guy playing a broken banjo? (Letters, May 30th and 31st) Hats off to Dublin Bus for banning such actions on its buses. But why stop here? Prohibiting also the use of mobile phones, iPods and other such devices would get the approval of the “silent majority”. – Yours, etc,
