Not all residents in Nursing Homes are elderly...you mention Hospice...if the place you are singing is a Hospice then your audience could cover all age groups. I work in a Hospice and we welcome visitors to entertain the patients, songs with a local theme go down well, for example those that mention the local industry, in our case fishing, sentimental ballads, especially the well known ones...Danny Boy, I dreamt I dwelt in marble halls Believe me if all those endearing young charms etc. Also humour is always welcome...preferably risque...though never crude.music hall songs and the like.. Make them cry, make them laugh...and have your diary ready for the next booking...could you come to Hull?
