Don't recall Bob Sinclair, Duffy etc being loved by anyone 30 years ago (or 40/50 years for many of us )
Many of todays venues are little more than pensioners disco's, a Social scene very loosely based around a few dozen 'Northern Soul' records where people can meet their mates and have a late drink with (or pull) people their own age. The Music is VERY much secondary to their main reason for attending.
