"They are back this year because they loved it so much the first time. They are already talking to me about next year's concert."
Ms Bowden said the event was planned to go ahead rain or shine, but she was pleased the weather played ball.
"It's just a nice thing to do on an Easter weekend, especially if you've had your fill of the heaving crowds on The Strand. This is cool, laid back and easy listening."
