4) 1976 The Forum (10 songs released as part of Hotel Calif. anniversary)
5) 1976 The Forum (22nd December full concert)- I do not have this, only saw this on Japanese websites- https://www.youtube.com/watch?v=MErwUK2drmE This link has 30 second snippets of 5 songs
5) 1977 Gothenburg ("Illegal Eagles")- Somewhat weird audio, but good quality , very rare as well https://www.youtube.com/watch?v=gB-s6PLCbmE
6) 1979 Budokan (the 25th of Sept.)- Great overall bootleg- https://www.youtube.com/watch?v=WL7D75TzgH4
