Just as a PS, here is the story so far, leading to my message above, as read on other boards:-

The Jupiter lease, after 15 years, was up for renewal. The owner decided that he'd rather open his own gogo bar on the premises.

Jupiter and ForFun on Silom Soi4 have the same owner so it was decided to move the jupiter business to their premises next to Balcony.

The land and property owner gave the boys and staff the chance to stay with him or move to Soi4 with their original boss.

How much truth there is in all the above I don't know but my message above makes it look likely true.
