Daevid Allen, a member...

...of the rock groups the Soft Machine and Gong, died at age 77.

Now, not only is that first name problematic (you don't suppose anyone ever misspelled it, do you?), but it appears to have been a self-inflicted wound. From his obit in the Times:

Christopher David Allen (he stopped using his first name and added the “e” himself) was born on Jan. 13, 1938, and grew up in Melbourne, Australia. 

It doesn't say, but I'm sure he had a good reason.
