Madonna appeared on the original 'hits' series iirc - I know Borderline did, as remember playing it lots on vinyl!
Hits, which became monster hits, then some other silly name, kept getting re-incarnated every so often. I'm sure wikipedia will fill in all the gaps..
In fact on about Now 10, there was some competition that came inside one of the record sleeves asking 'Which of these (3) artists (cant remember teh choices, sorry, it was a LONG time ago) has never featured on a Now Album'. The answer to this was Madonna btw...
Also, I thought Whitney had appeared - but then again may have been on 'Hits' (Track: How Will I Know?).. remember that on vinyl too!
When I were a wee lad, I built disco lights with 12volt scalectrix transform& relays!
David, may, just maybe showing his age.. a bit
*Apologies if I spelt scalectrix wrong ;)
