When he did early breakfast about 10 years ago he had a competition called 'throwing sugar lumps at the studio clock' and the jingle he used was the Thames ident - the words fit it perfectly
He does still have is anorak on - I think he's the only R1 DJ who has sung jingles, has pips at the end of the show and occasionally talks about VCS, minidiscs and CDs on air.

Georgina Bowman was reading the news instead of Dominic and managed to get all the beds out of sync, so at the end they had to go through them all to get to the right one for the weather!
Other presenters wouldn't have noticed if the weather was read over the news bed!
And of course most people wouldn't know that the "One Road Travel" jingle is very similar to the real Radio 1 travel jingle used in the late 60's based on "Drive my car" by the Beatles
