By 1963, their success was dazzling, thanks to "One Fine Day" and especially
"He's So Fine", which earned them a gold record and inspired George Harrison's
hit "My Sweet Lord" (which earned the former beatle a plagiarism lawsuit in
1976). Between 1963 and 1966, they made numerous television and concert
appearances in both Europe and the U.S., before gradually sinking into oblivion
in the 70s.
