I seen an advert for http://www.atthatgig.com in Classic Rock recently. Great site for anyone who's ever wanted to keep track of all the gigs they've ever been to. Once you've added the gigs you can add setlists, support bands, ticket scans, youtube links or whatever. Slowly working my way through 30 years of gigs. Don't have all the tickets, but been able to find most dates on the internet or work them out. Be good if more people joined the site - get some banter going etc. Have a look if you're interested.
