Dublin singer Mary Black says she felt guilty about being away from her children when touring and says she woke up one night and couldn't picture the face of her son Danny, who is now lead singer with The Coronas.

Speaking to Gay Byrne on tonight's edition of The Meaning of Life on RTÉ One, Black, who is about to undertake her farewell tour, also talks about her disillusion with the Church, her struggles with depression and her 'mystical experiences'.
