I have not been to a large concert for many years but the effect on the crowd when a familiar song is played continues to amaze me - the roar, the surge, the adrenaline - the power of music can be quite extraordinary.
The top quality cinematography of the footage projected on multiple moving screens behind the band was also noteworthy.
The band have been coming to Sheffield for decades where they have always had a great reception and the band were gracious enough to do a cover of Heaven 17's (We Don't need) that Fascist Groove Thang. Interestingly, the audience reaction to that particular effort was not as loud as that to some of the band's own songs. For the non-initiated (including obviously many in the audience), Heaven 17 was a major Sheffield act in the 1980s.
I am sure that Kiedis's new hairstyle is based on Phil Oakey's signature lop sided coiffure.
p.s. again for the uninitiated, Phil Oakey was lead singer for Human League and 2 members (Ian Craig Marsh and Martyn Ware) of this group went on to form Heaven 17.
