CD collecting/conventions etc. in the UK?

Here's hoping some of you UK fans out there can help?

As I live in the Channel Islands my only way of expanding my Elvis CD/books etc collection is by way mainly of buying off eBay, and this has worked very well to a certain limit & I've made some good contacts from certain purchases. But as I often visit the UK I was wondering if there were any specific outlets/shops whatever for Elvis CD fans? Also are there any monthly/yearly Elvis related conventions where fans can buy rare CD's etc? If there are any where does one get to hear about venues/dates in advance?

Thanks for any advice!

Come along to the Elvis "FAN FARE" ON Saturday, June 7th at THE RAYNERS HOTEL, HARROW MIDDLESEX. This is an event where actual ELVIS fans (not dealers) have booked stalls to sell off their Elvis products.
