A Christmas song is set to be released by education charity The Music Man Project and the Royal Marines' band, in tribute to Sir David Amess.
Called 'Music Is Magic', the single will be released on 16th December to raise money for disabled musicians.
Sir Amess, an MP for nearly 40 years, was attacked and killed during a constituency surgery at Belfairs Methodist Church in Leigh-on-Sea last October.
Founder of the Music Man Project, David Stanley, said the single was a fitting tribute to the MP, who was the charity's president and was heavily involved in the charity for over 20 years.
He told PA News agency: "He was our biggest champion.
"Those with learning disabilities will often have a physical disability as well and they've got lots of challenges.
"They're the sort of last to really achieve equality in that respect. Because of the nature of their learning disabilities, you've got many adults in particular out there have got no way of changing their own destiny.
"So I'm doing this through music by putting them out there and David believed in that and he really believed in them."
All proceeds will go to help supporting learning-disabled people across the UK.
