To kick off the final competition episode of 'The Voice,' the four celebrity coaches performed a rendition of the Queen and David Bowie song 'Under Pressure.' The song was chosen to represent the pressure the final four contestants were under tonight.

All four coaches -- Maroon 5 singer Adam Levine, pop superstar Christina Aguilera, R&B singer Cee Lo Green and country crooner Blake Shelton -- walked downstage as they sang the opening words together.

The singers then traded verses, with Shelton taking the first solo and Levine and Cee Lo following. Aguilera once again showed off her vocal range with a number of histrionic notes throughout the song.

While not completely polished, the performance was an improvement over the four coaches' chaotic Queen medley of 'Bohemian Rhapsody,' 'We Will Rock You' and 'We Are the Champions' that they performed a few weeks ago.

Not a bad attempt at 'Under Pressure,' but we here at Ultimate Classic Rock would rather hear the Queen and David Bowie original a hundred times before hearing this latest rendition.
