Wing wizard Ashley Young rescued a draw for Villa in front of England boss Fabio Capello. The Claret and Blue put in a sketchy first half performance and went behind on 68 minutes as Roq of the Rovers, Santa Cruz struck.
But five minutes later Gabby Agbonahor won a free-kick on the edge of the box and Young curled in a pearler to draw Villa level.
Marlon Harewood nearly won the game for the hosts but the ninja turtle lookalike saw his header crash off the bar.
In truth a draw was a fair result as the game lacked any real goal mouth action.
The first half saw very little flair or vigour as Blackburn matched up well and denied Villa any real opportunities. Samba and Ooijer erased any chance for Carew and Agbonlahor to make an impact.
Rovers did get a gift from Nigel Reo-Coker on 23 minutes after the midfielder, who had a torrid afternoon, gave away a penalty. He clumsily fouled David Bentley in the box and Matt Derbyshire stepped up to try and put the away side ahead.
Many would have thought Bentley would take the kick but Debyshire was determined. His desire wasn't rewarded though, as his former England Under-21 teammate Scott Carson guessed right to stop the shot low down to his right.
Carson was the hero in front of Capello leading to chants of England number one, but typically he almost made an error straight after as he nearly dropped the ball at the feet of an attacker. Luckily the defence cleared the danger.
The second half started in an equally cartoon manner for Villa as the passing from Reo-Coker and Petrov was at times laughable.
The Bulgarian midfelder was soon replaced by the in form Marlon Harewood. The striker, who claimed an acrobatic goal at Liverpool, was soon in the thick of the action.
He quickly picked up the ball and a jinking run ended in Villa's first effort on target, albeit a weak one.
His arrival placed emphasis on attack for Villa but they left the defensive door open. Rovers took full advantage.
Curtis Davies misjudged a through ball and ex-Blues boy David Dunn struck towards goal. Carson parried but Roque Santa Cruz was on hand to put away the rebound.
It was a lucky break for Blackburn who had hardly warranted a shot let alone a goal. A speech bubble above Martin O'Neill murmured discontent and showed what all spectators were thinking: How are we going to get back into the game?
But just five minutes later parity was restored. Roq of the Rovers moment in the spotlight was short lived as Young of the Villa took centre stage. Fabio Capello must have been impressed as the winger lashed in a 20 yard free-kick which made the wall look invisible.
Marlon Harewood, who is unlikely to be in the International recogning, nearly won it for Villa with a powerful header but he hit the bar. It was Young's day though and he has posed the question to Capello.
Could this cartoon end with a call up for Villa's very own Merlin? It should do!
