I was flipping through the channels on the television channels Saturday night. I can across a John Denver concert that PBS was airing. My grandfather had a John Denver cassette tape of another John Denver concert that I would tape a lot when I was young. I do not know what happen to the cassette tape but I did but a CD copy on the concert several years ago. Seeing the concert and hearing the songs last night brought back some great memories of time with my grandmother and grandfather.
