We have not been to the theatre or live lounge yet, but TBH we find the best evening entertainment is in the Piazza (Atrium to us), and the quality has been excellent.
A duo playing violin and cello covering popular music from classical to pop, ans the violinist is one of the best I have heard.
The party band, Asian soul with a philpino vocalist who is excellent, she hits all the high notes without any screeching, and they had the dancefloor heaving the other night
Plus we have had a brass section from the orchestra doing New Orleans jazz and dance music, whose philpino trumpet player would have starred in any 30s, 40s or 50s big band.
Then yesterday an ensemble of all three had the Piazza crowd enthralled with a wide selection of music, culminating with Bohemian rhapsody with asian sou'ls lead guitarist giving an excellent imitation of Brian May at his best.
The quality of all these musicians is way ahead of anything we have seen on P&O recently, where the excellence of one of the Pulse singers can be let down by the other, and no real stand out performers among the instrumentalists.
