I was invited by a school friend, Simon Heaton, Good on you, to go and see a band that at the time I had not even heard. Made the right choice and went along not knowing what to expect. They walked on stage, Plant apologised for having a cold, then went into Immigrant Song and put in one blistering performance. It was a totally life changing experience and introduced me to a world of 'underground' music that I didn't know existed. Zeppelin have been Gods ever since. Thanks.
