Great musician, did his time in the big bands and, by all accounts, was a very fine trumpet player (I'm not qualified to judge). And he made a lot of money, so therefore he could have had no artistic merit whatever! (Irony there)
The clue is in the fact that he was a professional musician. They all compromised - even as uncommercial a band as Mick Mulligan played dance music - read Owning up if you don't believe me. I saw Terry Lightfoot play once in the late 70s - he played alto a lot of the night, because it was a dance.
Ball and Bilk (in particular) turned me and many of my mates as early teenagers into listeners to jazz and, in some cases, players. A lot of it was about the band's gimmicks - bowler hats, striped waistcoats - even Confederate Army uniforms - but we were fourteen!
I grew out of trad and started listening to modern, but eventually came to a broader view of jazz. But for the start in the music - listening and playing - I have to thank those guys. I owe them an eternal debt of gratitude.
