Paul Lewis, of Priory Jones & The Mission, said reaction to the song, which he wrote, recorded and uploaded to the internet after hearing the news had ‘blown him away.
The tribute was initially planned for release in May but was held up and is now available for download on Spotify, iTunes and other online retailers.
Said Paul: “Watching the events unfold on the news I was completely shell shocked. I could not believe what I was witnessing.
“Images kept going round and round in my head and I was trying to make sense of why and how someone could act in such a way.”
The download costs 79p and all profits go to Help for Heroes. To give the song a listen visit www.chad.co.uk.
