The audience in Oslo's City Hall, which included the Norwegian royal family, listened raptly, applauding often, standing to clap when Ms. Aung San Suu Kyi entered the hall and when she finished her speech, which was at the same time modest, personal and touching, an appeal to find practical ways to reduce the inextinguishable suffering of the world.

'listened', 'applauding' and 'standing' are parallel. Why is there no AND before 'standing'.

or am I wrong in saying these 3 are parallel.
