Possible ;yes, but acceptable ? not really ! My most disliked instrument in the Morris world has to be the badly-played trombone -in fact,even somebody such as George Chisholm would have been able to add little other than his evident virtuosity ( and then only as an embellishment rather than a terpsichorean necessity ).Of course , I have nothing against either euphoria or tromboniums ,having played in Royal Naval Volunteer Bands for 11 years, but their use for Morris ; no thankyou !!
