Many thanks for your gracious message and compliment implied by wanting to perform my songs.
Thanks also for being so kind as to ask my permission to sing them - 'though no permission is necessary. I'd appreciate credit, where appropriate and knowledge of any recording, etc.

Go for it - and good wishes. Hope to meet up with you (all), and possibly even sing with you, before too long. How about Bay City, MI?

Cheers, 
Tom
