Deletion of Ken Coomer

Comment: this seems to meet #6 {{tq|is a musician who has been a reasonably prominent member of two or more independently notable ensembles}}.  The rule is useful partially due to the difficulty in choosing a redirect target in this case.  I can't find any in-depth biographies, but coverage like https://books.google.com/books?id=a3yp8jLtGRAC&pg=PA262&dq=Ken+Coomer&hl=en&sa=X&ved=0ahUKEwiylLv-lv_aAhXs7IMKHWT1B0IQ6AEIPTAE#v=onepage&q=Ken%20Coomer&f=false should be enough in this case
Stance: keep
