I've been practically mainlining ISIHAC lately, working my way through the past series, and was really hoping I might get to see a future series being recorded. But there probably won't be one now. I'll miss Humph's delightfully mischievous humour.
I'll have to actually find some recordings of his jazz work, and listen to that - I suspect I'd probably love it.
Anyway - RIP, Humph. You'll be missed.
