I have the feeling that there might be a string section on stage for this tour...Maybe a little section.
During his videos, PG stated several times how happy he was to see some familiar faces during the recordings. And I read somewhere (in uncut?) that there would be "new" musicians who are not familiar to play with Tony, Manu and David.
It would make sense for this new album as the strings seem to have an important part.
I wouldn't be surprised....
