I'd agree with the above comments. I remember that at the time pop lyrics fell (broadly speaking) into three categories:
There were the "boy meets girl", teenage love, run of the mill TOTP sugary slop lyrics.
Then there were the fantasy, wishy washy cosmic other world stuff of those 'orrible concept rock bands.
Perhaps the worst were the "white boy gets the blues" songs of those blues influenced rock bands, which became those witless "I'm a hot guy and I think with my todger" lyrics, so beloved of Led Zeppelin and the Stones imitators. It was refreshing when the post punk era ushured in a new generation of real songwriters.
I missed BS at the time, although I heard of them. Going by the clip, I would probably have enjoyed them.
