McTell, who is best known for his song Streets of London, recorded The Unknown Soldier during lockdown. The song features orchestral contributions from the South Bank Sinfonia as well as poetry recitals from Sir Billy Connolly, Sir Anthony Hopkins and Liam Neeson.
The song has been created as a tribute to the Armed Forces community and provided to The Royal British Legion to help raise funds for this year's Poppy Appeal.
Donating online as part of the Poppy Appeal is now crucial to supporting veterans, Forces personnel and their families who have served and sacrificed throughout the generations.
Please donate what you can. This year, your donations are more vital than ever.
