From the website:
4. Now, some sad news. I've asked Jim about Houston 77. He said that this concert will never be released, due to problems with sound, especially with piano microphone.
5. Then I've asked, if there any concerts from 70's that they gonna release on DVD. Jim mentioned only Hammersmith. I've asked - if there is any concert from 76-79 era. The answer was NO. There is no concert from this era, that could ever be released on DVD. Said, but true.


That's really really upsetting. Jim should release some from 76-79 for us fans, especially those not even alive yet at the time that want to see these concerts! :'(
