Tommy/WMG

Tommy is an alternate version of Pink from The Wall
In Tommy's version of events, the father survived the war in a POW camp and returned, only to engage his wife's new husband in a fight to the death, which traumatized Tommy and made him enter into a near-catatonic state. When cured of this state, he briefly becomes a quasi-religious figure, protected by guards that assault Sally Simpson when she tries to get up on stage with him. In Pink's version of the events, the father died, and Pink's many negative experiences led him to build a "wall" around himself to keep others out. As he descends deeper into psychosis, he imagines himself as a fascistic dictator. This sequence grew out of Roger Waters' concern at having once spit at a disruptive fan at a concert, similar to the incident with Sally Simpson depicted in The Who's rock opera.

Tommy is Jesus and Frank is L. Ron Hubbard.
Tommy represents the traditional religion and its more philosophical aspect while Frank represents the corruption of religion to be rip out of soul, packaged and sold as another good. And what better example for it that making him L. Ron Hubbard?

Cousin Kevin and Uncle Ernie are from Frank's side of the family
There is no way in HELL that Kevin and Ernie are Nora Walker-Hobbs' blood relatives!
 * They could be. She was incredibly unhinged.
 * In an interview, Pete Townshend stated that Ernie is not really related to the Walkers.

The Local Lad/Champ is from a rich family and doesn't have a real job...But he's not an idiot.
It would exlain how he had enough time and change to become the best Pinball player on every machine "from So-Ho down to Brighton".
