Well, as their contemporaries The Beatles said -- "You say goodbye, and I say hello."
So...hello, hello. In 1993, The Seekers reunited with Judith Durham again still singing lead, and this is most of that entire concert, over an hour of material. And still in great voice. (It says "complete," though the description notes that some material has been deleted.)
By the way, much as all these videos of The Seekers might suggest that I was a massive fan, as I noted this isn't the case. I liked them whenever I heard them, but never bought any of their albums and never closely followed them. I just they were a good group, with a nice sound and enjoyable selection of songs. But what I particularly like is their story -- how they came together originally for just 10 weeks with Judith Durham as a temporary fill in, had a strong career for about five years when she decided to pursue her original interest, how she continued to perform and have a solid if limited career, mixed with some personal challenges, but that the parting was amicable, and eventually a quarter century later they reunited and even recorded together again-- and (as noted) in as good voice as ever.
