As well as cheering on the team, JP wants a big turnout of fans to prove that playing home matches on Saturday evenings and Sunday afternoons would be a mistake. The club worked hard on its 'Friday night is rugby night' campaign and in today's edition of The Times, JP claims any change would be a mistake.
"It is when we have always got our best support, you get all sorts: students before they go for a night out, people coming straight from work, kids after school. Glasgow is a special position, you have to work out when the people want to come and put the games on then. You are not going to get a lot of new people in a place like this, which is really a football city."
The club has two Saturday evening games lined up at the end of September, but while it is too late to change them, it is not too late to change dates later in the season and with supporters groups in both Edinburgh and Glasgow venting their anger at plans to move the games, there is a powerful lobby backing his call.

The Herald also reports JP's views on Friday night rugby in Glasgow: "It is a very different city from Edinburgh, very much a football city, so you have to put rugby on for them when they want to go and watch it."
That flies in the face of recent messages from Murrayfield's marketing department which claimed shuffling matches across Fridays, Saturdays and Sundays would help attract "a family audience".
JP, a full-time professional player for seven years who hails originally from Dundee, lived for several years in Edinburgh so he knows all perspectives of the Scottish rugby scene better than most.
In that context, then, it should be noted that Allan Munro, the SRU's new chairman and Gordon McKie, the new chief executive, have promised that no commitments made before they took over are set in tablets of stone.
The new regime has already impressed those in the Glasgow organisation by visiting them to assess their working conditions and invite views on how they could be improved, something that has happened all too rarely in previous years.
Yet, after the weekend's disappointing pre-season visit to English Premiership side Newcastle Falcons, JP acknowledged players have enormous responsibility to lift morale particularly with a new emphasis being placed on the pro teams.
Among the few players who went on the record to defend Matt Williams, sacked as Scotland coach in the spring, JP none the less accepted there had been too much emphasis on the national side.
"If we get the pro teams right then when we go into the international team it should just be down to fine tuning," he said. "It should be the guys in the pro team that is winning most that go into the national team because confidence breeds confidence, so the best way is to put everything into the pro teams and get us winning."
JP said the weekend defeat at Newcastle offered a reminder of how much that is about mind-set. "We have had a good pre-season but we have to start acting like we believe in ourselves and that we are the big physical side that we are.
"We've got to have a bit of arrogance about ourselves," he went on, echoing a message from Edinburgh coach Frank Hadden.
