Through interviews with members, colleagues, and family members of Thin Lizzy band, as well as anecdotes about the man himself, Emer Reynolds' documentary 'Songs When I Leave' depicts Phil Lynott's journey from a young black boy living in the working class of Dublin in the 1950s to his debut as a rock star in Ireland. This movie focuses on some of his iconic songs, from the initial success of 'Whiskey in a Jar' to the popular songs of the mid-1970s such as' Prison Break ',' Waiting for Alibi ', and of course,' Boys Back in the City '. This song ranked first in Ireland, tenth in the UK, and became popular in the US and Canada, quickly making Thin Lizzy an international superstar. As a songwriter and poet, Lynott infused her roots into these songs, creating narratives that resonate with fans around the world. Furthermore, 'Songs When I'm Not Here' traces Lynott's life beyond rock music as a father, husband, son, and friend. This movie tells the story of Phil's wife Caroline Taraskovitz, his daughters Sarah and Catherine Lenot, as well as conversations with Thin Lizzy band members Scott Gorham (guitarist), Eric Bell (guitarist), Darren Walton (keyboardist), and Midge Ure (guitarist of Thin Lizzy and Ultravox). In addition, Huey Lewis (Huey Lewis&The News), James Hetfield (Metallica), Adam Clayton (U2), Brush Shiels (Skid Row, 1960s), Terry O'Neill (Thin Lizzy's first agent), Suzi Quatro, and others were interviewed in the film to gain a clear and extensive understanding of his life and legacy.
