We did a lot of outreach at Beatles events fan before launch. We donated copies of the game as giveaways at some fan events that we couldn't attend, we staffed Beatles Fest in Chicago, which was mentioned in this thread, and we recently teamed up with the Boston Pops to continue outreach to non gamers.
But, as I'm sure you can imagine, we're fairly limited in terms of demo staff and with GD:RB and RB3 coming out soon we've got our hands full demo wise. But that certainly wouldn't prevent us from being involved. If you're involved with a Beatles fan event, contact us and we'll do all we can to provide support. If you set up TB:RB at bar nights or other public events, let us know and we'll try to help with visibility. We can't always attend every fan event, but we'll support as many events as we can.
