Some 35,000 people gathered Saturday for an open-air concert at Tsumagoi resort in Kakegawa, Shizuoka Prefecture, featuring a reunion of the performers in a legendary 1975 show.

In the first concert, popular singer Takuro Yoshida and folk-singer trio Kaguyahime performed some 100 songs over the course of 12 hours in front of an audience of more than 50,000.

Yoshida, now 60, appeared on stage Saturday with a white guitar and told the audience, mainly males in their 40s and 50s, "I'm glad you're still looking good."

Yoshida, who underwent surgery for lung cancer in 2003, had asked Kaguyahime leader Kosetsu Minami, 57, to consider restaging the concert, and the group agreed. The show was sold out the same day tickets went on sale.

Many audience members sang along with the musicians as they reeled off their past hits.

"The singers and the audience were young and energetic" 31 years ago, said a 47-year-old man from Okazaki, Aichi Prefecture, who attended the 1975 concert. "Now we're older and mellower. I think we can enjoy this change."
