I am actively searching for tapes of Ireland's biggest band before U2, but cannot find anything. Anyone have any suggestions (links)?
Not sure if this is what you're after. http://isohunt.com/torrents/?ihq=Thin+Lizzy Videos, rare stuff and more. Not sure about live stuff though...
Here's a fantastic site for other bands bootlegs... http://www.guitars101.com/vb/bootlegs-other-bands/ Use the search facility - there's quite a few Thin Lizzy shows there if you scroll through. In fact there was a show from Glasgow 83 posted on there today.
