I saw Lindisfarne in around 1975 at my uni. We hardly got any decent bands and I really wanted to see them. Started drinking in anticipation early and though I was there I remember not a thing.
1st - Amazing Blondel Royal Festival Hall 1972ish
Worst - Leonard Cohen at the Brighton Pavilion (can't remember when). Sorry to Leonard fans but it was just a mumble-fest/dirge.
Best - Bowie, Worthing Assembly Hall 1972 ish
