I think there's some nods to Thin Lizzy in the solos on Death of the Celts, there is definitely very Brian Robertson like phrases at the start of Adrian's solo, and he is the biggest Lizzy fan in the band, so I definitely feel that's on purpose. I think there is some in Janick's solo too but that might be my imagination. I also think Dave is invoking his Clansman chorus fill in his solo too on purpose.
I wholeheartedly agree on the Brian Robertson influenced bit!
