I would say 'Yes' if you are a concert fan - soundboard, audience recording, or whatever, it doesn't matter so if you prefer Elvis in his final era then I think that every concert holds something in store for you. Obviously you'll like some more than others.
I prefer 'It's Midnight' to 'Tucson 76' and that is due to the varied song selection of this FTD release. Plus, it's always great to hear Elvis' live rendition of the title track. But, 'Tucson 76' does hold a nice wee jewel in the guise of 'Danny Boy' - worth the price of the CD alone.
