Westminster Abbey Free Organ Recital
 

I read there is a free Westminster Abbey Free Organ Recital on Sundays at 5:45. Is this worth going to?
Would this be a good way to see the inside of the Church?

I see any services as an additional way to see the church, not the main way. You obviously will not be able to explore in the same way that you can when visiting as a tourist.

church services/evensong/organ recitals are wonderful -- but do not substitute for touring the Abbey (or St Pauls for that matter)

You access is very limited and can't wander around. Depending on where you get a seat you might get a glimpse of the choir - or not.

Thank you for the opinions

Bindrey, you might consider taking the London Walks tour of the Abbey for a great way to see it.
