From 1998, the breakfast show on Horizon Radio was presented by "The Morning Crew", made-up of Trevor Marshall, Andrew Whyatt-Sames (better-known as "Cueball") and Ros Hale.
Cueball bowed-out in 2008 in order to pursue a career as a business psychologist, shortly before the Heart rebrand, and was replaced by Wes Venn, who had previously presented the drivetime show.
He was subsequently replaced by Joe Rudd; Lucy Ellis fronted Heart Drivetime up until the station's closure.
On Friday 2 July 2010, Ros – the last connection to the Horizon Morning Crew – left the Milton Keynes station.
On bank holidays, including Christmas Day, Wes and Ros presented the show in its normal format but from 8am to noon.
