One of the first live gigs I went to in Germany was Santana.
A mini bus load of us drove down/across from Detmold to Dortmund (on a Sunday I seem to remember).
On the way there all I could think was 'would actually Santana be any good watch live'.
I should not have doubted their talent, it was a fantastic gig.

I was racking my brains the other night to remember another surprise gig I went to and it came to me today, Manfred Man (can't remember if they were using Earth Band then) but they were excellent.
My worst was Dire Straits, they were dire-bolical.
Bowie in 82/83 was fantastic (Serious Moonlight Tour)

Managed to get back stage with Toyah Willcox in Herford because security thought we were roadies as we were wearing "CREW" tea shirts.
A few weeks later we saw the Cure at the same venue and they must have played an extra hour of encores (or zugabe as the Deutch say).
Infact 'the Scala' Herford was one of my favourite venues. It was a converted Cinema so not too big (but you got a good view) and as a result no Mega Bands played there but with Punk/New Wave growing in popularity in Germany (4 years behind the UK) it was the place where we watch the UK Subs, Toyah, the Cure and Psychedelic Furs to name a few.

Best big venue for me was the Westfallenhalle in Dortmund.

It is a circular auditorium (and veldrome!) with standing space in the middle which could be accessed from many entries from the corridor full of bars, eateries and toilets so access and going to and fro for 'refreshments' was never an issue.
Lived in Yobsville for 31 years now and I have never be to Glastonbury Festival.
