Watch: The Last Shadow Puppets cover Arctic Monkeys' '505'.

During their set at Rockwave festival in Athens, Greece this past weekend, The Last Shadow Puppets delighted fans with a surprise cover of the Arctic Monkeys' tune, '505'.

The crowd was so happy! It's adorable how Alex lets them sing most of the song themselves.

Watch the TLSP rendition of '505' below, as well as some amusing footage of Alex Turner singing about getting cheeseburgers thrown at him...
