The boyband performed a reworked version of their 2006 number one single 'Star Girl' - titled 'Star Boy' - for the BBC Radio 1 DJ's last ever breakfast show this morning (September 14).
The original track has been played on every Friday on Moyles's show, as part of their 'McFlyday' feature since 2010.
The Chris Moyles Show was given a big send-off yesterday for its penultimate show, with guests including Ant & Dec, Gary Barlow and James Corden.
Nick Grimshaw will take over the coveted Radio 1 breakfast show slot on Monday, September 24.
Moyles will soon appear in an arena tour of Jesus Christ Superstar as King Herod, and will then embark on a live theatre tour with his Radio 1 breakfast show colleagues.
