Interesting.

I do have the second demo as an SGU file: "_BOOG40S Demo 2 - (ALLREALTRACKS-40sBoogiePiano,ElBass,SaxTenorSolo,RealDrums)".

However, the actual style does not appear to include the Sax at all so I don't know where that second style came fro.

I can find both '_BOOG40S Demo' and '_BOOG40S Demo 2' SGU files on my system at these two locations:
E:\bb\Demos\RealTracks - Demos
E:\bb\Demos\RealTracks - Demos\RealTracks180 Demos - Classic Jazz Piano

They are all dated as December 2012
When I load the Song Demo for the style, offers a choice of two styles. If I choose Demo 2 it removes the Sax and offers a message. Selecting Undo brings the Sax back:
