While in the beginning his art, singing, and songs were the main thing, as time went on, and I suppose as he became more well off, if you can ever use this term to describe a musician, he became best known for his work with kids. Sick kids, disabled kids, kids with terminal illness, and others not expected to get better. AFAIK, these efforts were what got him knighted to Sir Rolf, just proving that for all the antics, his heart was really in the right place.

Most of us forget that he originally came to England as a commercial artist, and began his singing career busking and/or singing around in gatherings of ex-pat and lonely young folks from Oz and New Zealand, where his songs brought a bit of home to them. I seem to remember Tie me Kangaroo Down as making it big in the US in the late 50's-early 60's, and it was great when I got to England and found him doing TV shows that were being broadcast in the south east part of England. I think they originated somewhere's in the Midlands, and were shot in what seemed to be an ex-auto showroom with its large set of windows opening onto the street level. As I recall, they were closed off with drapes, but Rolf would frequently open them and gallon cans of paint in one hand and a house painter's brush in the other, caricature great hordes of passersby looking into the studio at the show, from the back of the stage.
