flattened "blue notes" for expressive purposes "was a strong feature of Frankie Kennedy's playing with Altan." Kennedy played flutes made by Chris Wilkes and Patrick Olwell. Frankie Kennedy Winter School Established in December 1994 in remembrance of Kennedy and with the intention of keeping both his memory and the music of County Donegal alive, the Frankie Kennedy Winter School (Scoil Gheimhridh Frankie Kennedy in Irish gaelic) was an annual series of classes which was held for almost two decades in Gaoth Dobhair (Gweedore), County Donegal until the last edition occurred in December 2013–January 2014. In 2004 the school released a CD compilation of solo Irish flute played by a "who's who" of contemporary masters of the instrument, called An Ghaoth Aduaidh/The North Wind, in honour of Kennedy. Kennedy's mother Agnes still attends the festival annually and is close to Mairéad's family. Memorial St. Oliver Plunkett School, where Kennedy and Mairéad taught, planted a tree in their Garden of Peace in memory of Kennedy. The school's staff and pupils planted a Wild Pear, used to make flutes, in his honour. A plaque was also created, with the following inscription: On the day of the planting ceremony over 400 of the school pupils, many past pupils and staff members put on a very special day-long marathon festival of music, song and dance. There was a three fold purpose. We wished to honour Frankie. We wished to celebrate his life in the way he enjoyed most, showing the joy and happiness that we can get from music, song and dance. Thirdly we wanted to raise funds for cancer research and the Hospice Foundation. We achieved our aims and had a marvellous day in the process. Mairead and Altan's Dermot and Ciaran came and played for huge audience who had gathered. It was at once a very poignant though terribly happy day. Tributes Dozens of songs have been written and recorded about Kennedy, including the following: Dan Ar Braz, then a member of the band L'Héritage des Celtes, wrote, recorded and released the song "Left in Peace" in L'Héritage des Celtes's 1995 live album En concert as a tribute to Kennedy. Altan have recorded several songs lamenting Kennedy, including Mairead Ni Mhaonaigh's jig "A Tune for Frankie" (which is the last track on Altan's 1996 album Blackwater) along with "Time Has Passed" and "A Moment in Time" (which are two tracks from Altan's 1997
