Roger Daltrey stunned guests at a recent wedding reception after he hopped on-stage to serenade the bride and groom.
The singer joined rock band Thunder to belt out his band's hit Substitute for newlyweds Alejandro Londono and Angie Jenkinson.
And Jenkinson - who met Daltrey through the Teenage Cancer Trust, which they both support - insists her family and friends loved her superstar wedding singer.
She says, "The band did rehearse Substitute with him just in case he was in the mood to sing on the night. They had played together once before at a charity event. When he got up, everybody went mental.
"After he did Substitute he wanted to do more but they hadn't rehearsed. I have known Roger for years through the Teenage Cancer Trust. He is like family."
