Mr Pratt, who also lived in Maldon before moving to Canterbury 10 years ago, said he fell in love with rock ‘n’ roll after watching Bill Haley on TV, and first picked up the guitar at the age of 10.
Ryder came to prominence during the Covid-19 pandemic after his lockdown singing videos caught the eyes of millions on TikTok.
He went on to represent the UK at Eurovision in 2022, coming second, and has just released his second album, Heartland.
Mr Pratt said playing with Ryder on 6 November was “exhilarating” and continued: “There are a lot of words just to describe how fantastic it was. It’s given me a boost in life.
“You never say never in this life because things do happen, but to think that my life would actually end up like that at Wembley is really a dream come true, and Sam made that possible.”
He said he taught Ryder at a studio in Heybridge for about a year.
