Oh. Well the last note of TROAE is Db, right? That's the same as the leading tone of Dm (C#). So I imagine that'd work out well.
Dm doesn't even have C# in it. Unless you're using the melodic minor scale.
The raised 7th scale degree is usually assumed when used in a dominant function.
And I watched the concert; they didn't do any sort of allision. At the end TROAE, the sound effects for The Answer Lies Within started then faded to the sound effects before LNS. It's enough of a break to where the notes don't matter. They could've done the alternate ending fine.
