Sister act Tori and Taylor Thompson went retro with their version of 'Boogie Woogie Bugle Boy' on week two of the live rounds on 'The Voice.' The sisters, dressed in retro, coordinated outfits, showed their strengths as a well-matched vocal pair with this old-fashioned song, as they operated on an endless supply of sugared energy. They made us (and the coaches) proud to be American.

Overall, the styling, the imaging and the entire package was highly entertaining, since the girls sang, danced, dressed up and had background support from a bevy of dancers. It felt like a Thompson Sisters show. Christina Aguilera labeled their leggy rendition "luscious"; She was sure to mention that all she saw were legs coming at her since it was a performance that relied on the moves as much as the sound.

Adam Levine dubbed the performance "good old fashioned entertainment" and praised Cee Lo Green for choosing that song for this duo.

The judges gave a universal salute to the ladies' performance. So did we. It was cute and sassy, without being too cutesy or overdone.
