The Gift of Years
Danny Spooner sang Eric Bogle's song The Gift of Years on his 2017 final CD, Home. He noted:
Written by Eric Bogle in 1990 for the seventy fifth anniversary of the landing at Gallipoli on April 25, 1915. The last remaining veterans were invited to return to the battlefield. The title was prompted by a letter which Eric had read from a Second World War veteran to his children. He thanked his friends, comrades & family.
Please find the lyrics for this song at Eric Bogle's website (PDF document).
