Jermain Defoe scored a hat-trick to help England storm to a 4-0 victory over Bulgaria in their opening Euro 2012 Group G qualifier at Wembley.
England took three minutes to begin the rehabilitation from their poor 2010 World Cup when Defoe smashed in a volley from an Ashley Cole cross.
He doubled the lead after 61 minutes with a left-foot shot and completed his hat-trick four minutes from time.
Adam Johnson, who replaced Theo Walcott in the second half, grabbed England's third after 83 minutes with a low left-foot drive.
Hart, newly installed as England's number one by coach Fabio Capello, justified that billing with three top saves as Bulgaria threatened.
The only blemish on an otherwise encouraging night for England came after 56 minutes when defender Michael Dawson was stretchered off with a knee injury.
