yeah, that has been the trend.
I'm thinking Sodom, Destruction, JBO someone like that.
My guess
They don't have a band yet...and Orga is on a desperate Search for a band of a size that can compare to Thin Lizzy....
This Secret show is a cover up so that we don't get mad that there is no replacement for Thin Lizzy
Considering Thin Lizzy's slot over-laps Running Wild, to put any heavy / power in that slot would be bloody stupid!
A perfect opportunity to stick a big DM band in to keep you bunch of whingers happy!
