Loads of musicians, and some TV people - as a culture freelance.
The majority have been nice - but I am meeting them in a pre-arranged interview situation, so we all know what we are doing, and the parts we play.
Some do go over and above that remit though -
I interviewed Roger McGuinn from The Byrds at the launch of his new seven-string guitar made for him by Martin. After the interview was finished, Roger and I sat in the lounge of the hotel, and he offered me a chance to play his gorgeous - and unique - new guitar.
Having confessed that, despite being a writer about acoustic instruments, and knowing vast amounts about them and the people who play them, I don't actually play the guitar myself, Roger cheerfully offered to demonstrate the sound of the guitar.
Roger McGuinn of The Byrds then played and sang Mr Tambourine Man just for me!
Now that was an experience!!
