having looked through the topics in this section I couldn't find anything similar except for the one where the lyrics for “I Fall Apart” were discussed.
So I thought it would be good to have a more generalized topic.
Now I'll try to make the point clear.

As a non-native speaker I sometimes find it rather hard either to catch some words in songs or to understand what is meant. Of course in the latter case the meaning cannot be always explained when it comes to the artist's vision. Sometimes only the author knows what he or she meant.
However, certain things CAN be explained or, say, commented on by those who are aware of the context, background, allusions, etc.
As for the difficulties with catching the words.. Nowadays it seems easy to deal with the problem, for there are plenty of lyrics websites. Unfortunately, they are cannot be entirely trusted as there sometimes can be mistakes in lyrics and not very seldom in controversial places.
So, I would suggest to discuss here questions concerning Rory Gallagher's lyrics, if you have doubts as to the exact, not quite distinguishable words in songs or the meaning of certain lines, etc.
