Bob Seger wrote Rosalie, which was covered by Motorhead, who perpetrated The Ace of Spades, which was covered by The Bad Shepherds, who played Cropredy.
I know Thin Lizzy covered Rosalie, but Motorhead? Nevermind,Brian Robertson was in Lizzy and Motorhead,so that's fixed that...and of course,Wurzel of Motorhead played with FC.
John Sykes was also in Lizzy, and Whitesnake.
Three members of Whitesnake were in Deep Purple and via Deep Purple you've got the entire population of musicians in the world connected (including me!).
Hope Pete Frame is getting all this down.
