The man I consider the father of modern record production passed away on March 8th at the age of 90. Martin leaves behind an enduring and timeless legacy not only for his association with the Beatles, but the very heart of his craft, always an innovative and adventurous artisan, and as many will attest, a true gentleman.
Trevor posted a remembrance of Martin on his Facebook page last night:
I was so sad to hear of the passing of Sir George Martin.Some years ago he called me. He was doing a concert at the Hollywood bowl with orchestra and a band. He asked me to play and sing. It was an evening of Beatles music."Sir George Martin and friends". I sang a number of songs including Golden Slumber and some other songs. It was a magical evening. He was one of a kind. He was brilliant, kind, and just a wonderful human being.
The end of an era. Loved you Sir George.
Never to be repeated.
Trevor is actually referring to this 1999 performance:

It's fitting that Trevor sang "Golden Slumbers" because as we know, you can hear just a bit of the beginning of that song at the end of the demo version of "Walls" - which proves he definitely knew it well.
Update: thanks to the search-fu of another fan on Facebook, there was raw rehearsal footage which did include Trevor singing "The Long and Winding Road" at the end of the clip, around the 00:48 mark, but unfortunately the video has now been deleted from YouTube.
