Wishbone Ash exist in two forms and still perform. I saw them in York some years ago and enjoyed them enormously though they were VERY loud.

The only person I remember from IF was Dick Morrisey who I saw various times with Jim Mullen (who a band member I play with knows quite well through his dad).

Chicken Shack lost Christine McVie to Fleetwood Mac but still exist and are playing in Hessle next month. I wonder if Stan Webb still has his 200' guitar lead that he used to wander round the audience with?

Most of the music is still easily accessible.
