From Zappa Wiki Jawaka
Eric Allan Dolphy (Born June 20, 1928 Los Angeles, CA. Died June 29, 1964 in Berlin, Germany).
One of Dolphy's most influential, and highly regarded, albums was Out To Lunch, a phrase Zappa used in the lyrics of Oh No, in 1964. Shortly after the album was released Dolphy died from undiagnosed diabetes, while touring in Europe with Mingus.
Dolphy's name, and work, popped up again as a theme The Eric Dolphy Memorial Barbecue on Weasels Ripped My Flesh in 1969, and it is claimed that part of the cover design for Burnt Weeny Sandwich was originally intended for an album by Dolphy that was never released.
