Watch: Tongan schoolboys serenade Prince Harry with harmonic rendition of 'Swing Low, Sweet Chariot'

Prince Harry was given a friendly reminder of home during his activities in Tonga today, thanks to a schoolboy choir's harmonic recreation of a classic English rugby anthem.

While in Toloa on the island of Tongatapu, the Duke of Sussex was serenaded by boys from Tupou College singing "Swing Low, Sweet Chariot".

The royal appeared to enjoy the rendition too, joining in in between handshakes with numerous guests and fans.

Prince Harry and wife Meghan are wrapping up the Tongan leg of their tour today before heading back to Australia this afternoon.

They arrive in New Zealand to finish the 15-day tour on Sunday.
