Glenn Shorrock still had lots of hair on his head back then. These days I'm sure Glenn puts a bit of fertilizer on his head in the hope his beautiful hair grows back again. I'm sure he was wishing his hair would grow back when he did that album titled "Rise Again".
I never seen him on cable tv over the years. I don't know what station he would have been on. I don't know where these you tube videos came from, what they were recorded from. Maybe they came from cable from the United Kingdom or Australia.
