Let the prepared tea cool completely. In a large plastic container, mix together the cooled tea, thawed frozen lemonade concentrate, thawed frozen orange juice concentrate, Bourbon, sugar, and 6 cups of water. Stir until the sugar is dissolved. Freeze the mixture in the plastic container until semi-frozen. When ready to serve, scoop the Bourbon Slush into a glass. Garnish with pineapple chunks, cherries, or a sprig of fresh mint, if desired.
