As for the Paradise Ballroom gig from Boston, 4th November 1978 gig I believe you refer, great isn't it!?
There was a gig two days later broadcast on radio too I believe, which is quite hard to get in complete form.
The Boston gig had been bootlegged from a radio broadcast, but the Wolfgang's Vault recording here is great as it contains Detroit 442, which was less widely available before, and also the tracks that didn't make the original broadcast -
Denis
I'm On E
Will Anything Happen
Youth Nabbed As Sniper
Once more I - and I'm sure many other Blondie fans - would strongly urge that a payable download is available, as it would be in greater quality and away from a computer too.
