There is such a thing, but I'm unsure if they're doing the game tonight. It's run in collaboration with the uni, and the students will be in the middle of their six-month summer break at the moment.
Same goes for St Mirren radio (available via the TuneIn radio app) - they do most games, but it's a bit patchy, and I wouldn't hold out much hope for them doing this one tonight.
Your best bet might be to keep an eye on @bawarmy on twitter, which sometimes has a periscope running.
I'm glad we're playing Dundee, though - we need to be tested at this stage of the summer, not flattering ourselves against vastly inferior opposition.
