A few quick comments on the last few posts.

The Lou Reed concerts at the old Agora Ballroom were broadcast on WMMS, as were hundreds of other concerts from the mid '70s until 1984 when it closed.

Earlier this year there was an online article about restoring/remastering the Record Plant tapes.  Interesting reading.

Regarding Blondie concert dates, their official site has a comprehensive list here:

In addition to Retro Rock, the Tom Petty & the Heartbreakers 1978 Boston show was also on the King Biscuit Flower Hour so it should be a good candidate for Wolfgang's Vault.  They were popular in the Bay area and played a number of concerts that were Bill Graham productions, it would be nice to hear them if any tapes exist.
