I'm doing research for a book on Kay upright basses. Mr McCartney owns perhaps the most famous existing example, the bass Bill Black played with Elvis. I'm hoping to connect with someone who has access to or has documented this instrument, looking for details of its construction, modification and its Kay serial number. If anyone here can help or can point me to a source, I and thousands of Kay fans would much appreciate it.
