Thanks Tell It Right (((((Hugs)))))
Not really related to the thread (other than it being loosely related to your post)
I can't say I have ever knowingly listened to Petra, but they are referenced in a very funny song:
The Houseplant Song by Audio Adrenaline
Take two houseplants
And put them to the test
Set them both in front of speakers
And let the music do the rest
The first one you play Mozart
Or something lovely like that
The second one you play that Petra Or that MegaDeth.
Doesn't really matter what kind of rock it is...
