Brown trout blues Lyrics

Cover art for Brown trout blues lyrics by Johnny Flynn

I think this song is about being in a relationship that has run its course. Now one person is different, but feels trapped to stay:

I could be somewhere else I should be someone else but It easier just to play the same old game Of trying to forget my bloody name

They know this but feel 'stalled' by the other person.
