A way back when, a mate of mine was in a band looking for a new lead guitarist. They auditioned blokes with Zep's Stairway to Heaven - paying particular attention to Jimmy Page's big solo. This one bloke came in and he did it perfectly, got all the string bends spot-on, moved smoothly up/down the neck and was particularly adept at the top fret notes. Bang on, they gave him the nod - problem was, he was ordinary (at best) with anything other than Stairway to Heaven - just couldn't really manage it. They dumped him after the first three night gig - he went on and did his Stairway to Heaven stuff with bands that focussed on that song. He was eventually lost somewhere, probably drives a bus now.
The thing is, Logue probably understood he needs to be in a band that only plays Stairway to Heaven - he'll look like a real champ with them. Fair enough.
