Cara is a student at St. Mary's College in Derry.

"A lovely young woman with a wonderful voice," said Jane on Twitter.

Cara McGuinness is the eldest daughter of Martin McGuinness' son Fiachra.

"She wasn't planning on singing - she just got up and sang for the craic," said proud dad, Fiachra.

Martin McGuinness passed away after a short illness in March 2017.
