We all know about Team Banzai and of Dr B. Banzai being the Federated Suns 'warped' scientists, mech warriors and of course "Rock Band!"
Chris managed to portray this so well in "This was easier on tabletop", that I feel that some other bands from fiction (and fact) maybe able to make the "jump" to a successor state, and though being a band is key, they should have additional traits that would help that state.
As I started the thread I will go first :-)
Sabaton- Joakim, Par, Chris, Hannes and Tommy find themselves before Katrina Steiner days before Ian Davion makes his visit, they play for the Archon, display a vast wealth of information of a different (especially towards the end) 20th and 21st century. In time Katrina seeing what Team Banzai has done for her ally in House Davion endows them with sufficient funds to start an institute of their own. Sabaton being Sabaton does music and history vastly boosting House Steiner's Armed Forces Morale. As a metal band of course they fit well with the Steiner view point of even 'heavier' metal (all mechs are of course assault class!). For the recon element their former band mates from "Civil War" could broach the Steiner-Davion-Hegemony boundaries.
Those that know Sabaton know they are SWEDES and 'should' fit the FRR better, however with all the Kuritan influences on that state, I feel that they would be much happier with their Steiner Cousins.
Hanse "Archon Katrina please meet my polymaths Team Banzai"
Katrina "First Prince Hanse please meet my troubadours, court historians and 'Steiner Scouts' (with a chuckle and Sabaton's 100 ton mechs) Sabaton!"
Thank you.
