I discovered today these vids which are very interesting.
The first one comes way back from 1987 when Yeah! were playing live at a small venue, in Exarhia district, called 127 dB Club.
The video finds the band performing the song “Rain” with the following line up: Yiannis Drenoyiannis, Chrysa Pantazi, Vasilis Kaskabas, Costis Anagnostopoulos.
On the second vid, there is no live footage but just photos of the band Nexus while you can listen to their song
“Drop the Luv Bomb” taken from their 4rth and last album, “The Beat Syndicate“.
