Agreed, I'd love it. But even at the time Moyles's jingles were totally out of whack with the rest of the station - you had his classical Morning Movie stuff alongside the Pure Tonic RA-DI-OH-ONE stuff and it sounded very disjointed. Now Radio 1 sounds slicker than ever, I can't see them returning to cheesy jingles.
Maybe - if they can find a way to do it that doesn't sound naff and dated - they might bring back sung jingles. But I wouldn't hold my breath, like Ben, I reckon it'll basically be new versions in the same style as now.
Remember when it was actual news that they were getting rid of sung jingles? https://www.bbc.co.uk/news/entertainment-arts-19255742
