Over 16,000 fans turned out to see the Jambos dazzle following a week of rumour and speculation over whether they will be placed in administration after the collapse of owner Vladimir Romanov's Lithuanian bank Ukio Bankas.
But Tynecastle boss Locke insists the form of youngsters such as Jamie Walker and Kevin McHattie, both of whom were on the scoresheet against Saints, offers hope for the future.
He said: "It was a great afternoon and a really pleasing performance. We knew there was going to be a big crowd. We had to be up for it and give the fans something to shout about. There's a lot of positive things at the club. We had 11 under-21s stripped today.
"The off-field stuff is not something that I really concern myself with. I concentrate on the football side of things. I am delighted for the backroom staff and all the people behind the scenes.
"We are thankful for the support we are getting from the fans and delighted to give them a good result."
