Ayaya performing the piano-accompanied version of Melodies at Hello! Project 2007 Winter concert (Elder Club THE CELEBRATION.)
Edit:
There were two sets of Hello! Project Tour Winter 2007 concerts:
1. Elder Club THE CELEBRATION
2. Wonderful Hearts Otome Gokoro
Aya was in the first set, while Miki was in the second (with Morning Musume.)
This solo performance was at the Elder Club concert held at Nakano Sunplaza on January 7th, 2007.
On Jan. 27th and 28th, there were final concerts, called Hello! Project 2007 Winter 〜 Shuuketsu! 10th Anniversary 〜, at Yokohama Arena to conclude the tour. Those concerts had all the members from the two earlier sets, and thus both Aya and Miki were there. The two of them performed Melodies and Thanks! together at the final concert, which can be found here:
