Jazz vocal takes on Jacques Brel

[Rabshakeh]

Retrospectively Brel seems to have been highly esteemed in 1960s Anglo culture. But it seems to me that, barring the odd Nina Simone cover, there are very few versions of Brel tunes on jazz vocal tunes. 

Can anyone think of any? Or any theories as to why his music did not form part of the 1960s school of new jazz and easy listening standards?

I feel like there should be whole Jackie Paris or Mel Torme records...
