The Greek Radio Symphony Orchestra performs various Star Trek themes. In order of appearance:

1. Main Theme from Star Trek (The Original Series)
2. Main Theme from Star Trek: Deep Space Nine
3. The Inner Light from Star Trek: The Next Generation
4. Main Theme from Star Trek: Voyager
5. Main Theme from Star Trek: The Motion Picture

I understand this orchestra has been disbanded due to the current budgetary problems in Greece. Pity to hear that.
