Red Hot Chili Peppers tickets (x3) - 23rd June, Knebworth Park !

Hi, I have three spare tickets to RHCP on 23rd June at Knebworth Park. Will sell separately for £70 each, or £210 for all three. I bought six tickets for myself and some friends, but three have had to pull out, they come with refund protection insurance too in case of any cancellations. The actual tickets have not been delivered out yet, expecting them very soon and can exchange in person in central London (Green Park) during business hours or in Clapham North/Brixton/Stockwell after hours and weekends. Happy to mail in first class post for free to anywhere inside the UK once payment has been made via bank transfer. Thanks, Alistair
