Waarom de band zo heet? Geen idee. Hier een tekst van Martin Turner's website: September/October 1969
The new band spend several weeks writing and rehearsing at Miles Copeland’s home. A new name is also decided on - Wishbone Ash - the two words put together by Martin Turner from two separate lists of potential names compiled by the band.
