A couple walks down the street holding hands while a man plays music.
Two young people stroll down the street holding hands.
The couple in question could be of any age, I like to imagine they are old and happily married taking a stroll to keep their strength up. It doesn't imply that they are young at all, they could indeed be middle aged, old, etc.
