Mix tequila, triple sec, beer, lemon lime cola and lemonade concentrate in a pitcher.
Squeeze 1/2 of an orange, 1/2 of a lemon, and 1 full lime into the drink mix.
Slice the remaining lemon (and orange if you want) and put into the pitcher with the beer margarita.
Add ice to the pitcher.
Serve over crushed ice with lemon garnish.
