Volunteers from a hospital radio station entertained shoppers in a busy Hendon shopping centre.
Radio Northwick Park played requests for customers at Brent Cross Shopping Centre, in Prince Charles Drive.
They raised £227 for the charity, which broadcasts to patients in Northwick Park Hospital, Watford Way, Harrow.
Fundraising officer Hannah Ashman said: "This was our first appearance at Brent Cross and it was a true success.
“The shoppers were incredibly generous and we would like to thank them all for their support and generosity."
