This evening... vinyl only.

Once upon a time radio stations relied on pre-release vinyl. This is one such 7", from 1973, that presaged the release of the album 'Vagabond Of The Western World' (SKL 5170) that was not, as it turned out, destined to rock the world.

Given a couple more years things were to change dramatically in terms of the band; both its core dynamic and the public's appetite for such music. 
The two tracks on the other face of this are 'Gonna Creep Up On You' and 'Little Girl In Bloom'.
As things are going tonight is not going to get beyond 7" singles that I know/or had forgotten that I have. This is a song that, in all probability, you haven't heard for some time...
  

The original release of it  - VER 1 (1981) - sounds so very dated now, I think.

When genres melded...

At some point rock, hard rock indeed, developed a sensibility that included aspects of both UK folk and Americana; perhaps not both at the same time and almost certainly not in the same place.
That would probably be in the early 1970s and this is one of the albums that, I believe, was a trail-blazer although the band in question were actually heading in the direction of harder rock at that time.

This is Decca SKL 5170 (1973) and hard rock it is not!  It is still very good though...

Eric Bell was a victim of the changes but perhaps its time has come around again.  A bonus is that SKL 5170 came with an illustrated lyric sheet.
Even in later Thin Lizzy albums this traît was evident - Jailbreak (1976) is a very good example.  It was, on the face of it, a 'full-on' hard rock album but the subject matter was actually rather traditional...  It was also the album that finally saw them see some success in the US.
