I suspect most of its audience follows the band with a hardcore enthusiasm. It just DT's fan base, so I think a majority of concertgoers would be at least familiar with Raw Dog.
Watch Score again - half the crowd don't even know where Raise the Knife ends! I know DT are a cult band, but it's still a mistake to define its fanbase by its geekiest fringes. (That's us!) Scarred was dropped from the Chaos in Motion tour because it wasn't going down too well - Constant Motion persisted right through to the end of the BCSL tour.
Some of that's the format - I think Scarred's more Evening With friendly - but I don't think there's any day of the week you could run a "What do you want to see live - Constant Motion or Scarred" poll on this board and not expect Scarred to win by a landslide. We're a very warped portrait of the greater ticket-buying fanbase. I'm sure there'd be a lot of people in that room who'd recognise Raw Dog, but I also think there'd be a lot more who wouldn't. DT is just one band among many, and it won't necessarily be everyone's favourite band - just a band they like.
Equally, though, I'd argue that's
not a reason to shy away from playing it! They played Another Won every night on the 20th Anniversary tour. Most everyone in the crowd was probably hearing that for the first time, but I think it was absolutely worth dusting off. Don't Look Past Me's the song I'd like to see. They never played it, as all the backing vocals would make it nigh-on impossible to perform with just the one strong lead singer, but they're playing to a click track now, they can pump some of that stuff in.
