An acoustic duo from Watford performed an impromptu gig for shoppers in Charter Place on Friday.
"Big Heart", made up of musicians Mike Baxter and Samantha Harris played a set of well-known and obscure covers from the last four decades.
Ms Harris said: "We had a great time playing and were a real hit.
"People were really friendly and asking us to keep playing and singing as they were enjoying it so much. Always good to hear this when you are performing.
"It's hard for people right now so a few familiar tunes and some upbeat songs might just help the misery that is spending money."
