I caught up on my favourite series today and I was so shocked to find out one of my favourite songs was in there: In the City. I'm surprised that there hasn't been a young Eagles fan before who mentioned this, because the show is very popular among young adults. In response to the song being played in the intro, there is a whole discussion going on about who sings it: is it the show's creator Justin Roiland or Joe Walsh?
My first reaction was that it had to be Joe, because I'd say I recognize his voice anywhere, but so many people state that Justin Roiland sounds just like that. Also, whoever the singer is, he does some things I can't imagine Joe would do, very little details, so I would say it isn't him.
Another trivia I should mention is that Justin Roiland voiced the whole episode, so it would make sense if he sings the song too.
