5. Call My Name - Cheryl (2012)
This highlight from A Million Lights proved that Cheryl (note the removal of her surname) didn't need Girls Aloud anymore to stay in the spotlight. All she needed was an addictive Calvin Harris production, with a hook that would make you want to call her name. Top that with the irresistible choreography, and you get an amazing 'live' performance. Your definition of 'live' may vary.
