Come step into 1975 with me. Looking back and checking on Wikepdia I discovered that it was your average sort of year.
Terrorism was rife(IRA and rogue German factions), wars happening (Vietnam), bent politicians (Watergate trial) etc etc. Most of this was of no interest to me at the time. All I cared about was, who was No1 in the charts, and the influx of "fresh meat" that had arrived at the school youth club when the 2 Catholic boys that had been expelled from their school to ours brought along their pals! Such excitement!
I find that this song always cheers up a dull January day. Sing along.
