I think the track you were looking for on Nut 18 was "Nobody I Know", the track before it was BJ Kramer's "From A Window".
If you had a request line, I would have thrown in "The Game", composed (lyrics too) by George Martin and performed by Mary Hopkin (on Postcard).
The Nice track I play all the time is "America" (from West Side Story). The mono single version of "Azrael" is a completely different performance, and has a terrifically punchy mix, so I recommend it to anyone predisposed.
I sure did enjoy the show yesterday!
