Probably Blink 182 at the NEC about 4-5 years back. They came on stage over an hour late and then rushed through the set as if we were keeping them from something. Love Blink 182 but live they're not too hot.

Gutted. I saw him in the states a few years ago, his fingers were way slower than they were back in '67.

God! I remember them ..... they were bloody awful on record, never mind live!

And they looked pretty stupid too .....

Black Crowes 1991, the band were very good but for some reason a spoonhead started throwing coins at the band causing them to storm off. When the crowd realised that the band wouldn't return until the perpetrator was apprehended it was like a parting of the waves. The numbty was then dragged backstage for what hopefully was a severe beating

Panic at the Disco... my friend dragged me along. The band actually weren't that bad when they were performing but they were only on stage for one hour - and in the middle all of the band, except for the lead singer, went off stage for a "break" for fifteen minutes, leaving the lead to perform a few covers on his own with a keyboard. They didnt really talk to the crowd or anything; aside from the lead singer, the rest of the band looked like they couldnt care less and didnt want to be there.

Busted at a Party In The Park. They were on first and the racket was indescribable. My ears were ringing for a week!

Michael Jackson Wembley 1997 was so disappointing, I swear he was miming and he took 3 mintue break between each song. Came away feeling cheated.

or

Oasis at Milton Keynes 2005. They were having an off day and were blantently singing by numbers.

I had to go take younger siblings to see Peter Andre, words cannot describe how bad he was! He even did a Michael Jackson cover and made a comment how he believed he was the new Michael Jackson

The worst concert was my very first experience to live music.It wasnt the main act which was Supertramps crime of the century tour but the support act.It was some idiot on a acoustic guitar who was out of tune and boring with less than the average amount of talent,he went by the name of Chris de Burgh.
The following year i went to see Gallagher and Lyle And guess who was supporting them.Same songs still out of tune and still boring.Thank god he hadnt written lady in red at that time.
