That's one of my favorite Thin Lizzy songs!
Here's a live version from the time they had the new line up with Gorham/Robertson.
You can clearly hear they're still trying to "find their feet" with the twin guitar parts (at 0:40)
As iconic as the Jailbreak Live & Dangerous albums may be (and I
really like them), over the years I've come to prefer the Nightlife and Fighting stuff.
It's funkier and more raw.
Especially the live recordings from that era are very cool. There's some very good BBC recordings that have recently been released on CD.
