I hate concert promoters, here's why

In 1965, The Beatles played at Shea Stadium to an audience of 55,600, the largest concert ever at the time. The ticket price? $5.60. With inflation it would be more today, but I'm sure it was still pretty darn cheap
In 1996, Oasis played Knebworth, a venue with a capacity of more than 100,000. Over two and a half million people applied for tickets, the most in-demand concert ever in Britain, a record which still stands. They were supported by : The Charlatans, Kula Shaker, Manic Street Preachers, The Bootleg Beatles, The Chemical Brothers, Ocean Colour Scene and The Prodigy. Ticket price? £22.50
In November 2010, Jedward will play the Grand Hall in Kilmarnock. Jedward came 5th(?) on last year's X Factor. The Grand Hall holds around 3000 people. Ticket price? £22.50. Yes, you read that correctly.
Is it just me, or are concert promoters the worst people ever? I wanted to go and see Gorillaz in the SECC this year (which they later cancelled, the feckers*) but the ticket price stopped me. £45? Not even for a stadium gig? The cheapest ticket I've had (for an established band) is £20. £20 doesn't seem all that terrible, but I've had to pay up to £50 for stadium gigs. Again, these kinds of gigs are a once-in-a-lifetime experience (yes, bands tour again, but a stadium gig is a special thing, it's a whole day out) and it's not like you go to more than one a year, but when you compare the prices now to the prices of truly huge and iconic gigs from ye olde days, it's frightening. If I had a time machine, for the price of seeing Paul McCartney today at Hampden (£75!!) I could see The Beatles at Shea Stadium, Queen at Wembley, Oasis at Knebworth and Led Zeppelin at Earls Court. Yes, in a perfect world you could see 4 of the most iconic gigs of all time for the price of seeing the ginger Beatle singing 'Dance Tonight'. But we do not live and a perfect world. So, let's either invent a time-machine, or let's burn down the headquarters of DF Concerts and SJ Productions! VIVA LA CHEAPSKATE REVOLUCION!
Thanks for reading

*in a slightly related footnote, yes Gorillaz cancelled their gigs in Glasgow, Newcastle and Manchester to play in America. If you bought tickets for one of these dates? You can either have a refund, of you can TRY to get a ticket for the Liverpool date, and you'll be given a DISCOUNTED bus journey. Brilliant
