A little light entertainment.
All over Barcelona there are v street performers trying to make a few euros.
On the Ramblas there are many "Statue" performers, who are only too happy to have their photos taken, with you in the shot too if you want, but please remember to give them a donation. These are just a few of the ones I've seen over the years...
And if you're lucky you may find some musicians playing. One of the best places to see them is in the Santa Anna pedestrianised area.
Here is a group we saw on a recent visit to Barcelona. We stood a while listening because IMHO they're really good
