A St Albans Elvis impersonator stormed the Henley Regatta on a homemade raft last week.
Martyn Dias, helped by a four-piece band, sang for five hours straight for the guerrilla concert on Wednesday, June 28.
Mr Dias, who goes under the stage name Elvis Shmelvis, said: “My voice is still suffering.
“The rain held off all day and we were greeted all along the Thames by very happy men in their striped blazers, and beautiful women in their long dresses and exotic hats.
“It was probably my most memorable gig ever.”
The group set off on the motorised raft from Wargrave, up the Thames, and right through the Regatta, and then back again.
Mr Dias said they were stopped twice by police and asked to quieten down as the rowers could not hear their instructions.
At one point, they were even joined by former Radio 1 DJ Mike Read.
