Two Caribbeans aged in their 90s who came to Britain as young men described the Windrush anniversary service as "great" and "moving".
John Richards, 92, and 93-year-old Allan Wilmot sat beside each other near the altar in Westminster Abbey, just a few feet from Theresa May and other politicians.
Mr Richards who was 21 when he arrived on the ship in 1948 said he thought the service was "great".
He added: "It brings back memories yes, but I'm too old for the emotion."
Mr Wilmot, 93, met his brother off the Windrush, having come to Britain a few months earlier where he served in the Royal Air Force's air sea rescue team.
Proudly wearing his medals, he said he was glad to be able to attend the commemoration.
He said: "The whole thing was very moving. It brings back memories.
"I'm still alive to see it and that's the most important thing. A lot of my comrades are gone."
Mr Wilmot, who was invited to a reception at Downing Street on Friday afternoon, said he would be telling Mrs May: "I am happy that our efforts have been recognised."
With a smile, he added: "The British are never in a hurry to do nothing. But eventually they get around to it."
Mr Richards, who spent most of his time after moving to the UK working for British Rail, said he would celebrate by visiting the West Indians club, and might enjoy a drink of rum.
He added: "We are a happy people."
