William was "free" after his "breakup" with Kate Middleton.

During their dating phase, Prince William and Kate Middleton briefly split up in 2007.

William and Harry can be seen introducing acts in a rediscovered tape from a Princess Diana tribute concert in 2007.

Judi James' analysis revealed William's awkward dad-dancing and Harry's expressionless reaction.

Kate was seated several rows back, most likely as a result of the break-up.

Harry's reaction was that of a teenager whose father was humiliating them at a party.

This was most likely a small swan song before marrying Kate.
