I just came across a fine article at "The Best Years of Music" on '60s R&R singer Del Shannon. I hate to date myself (though I save $50 a weekend when I do), but I personally learned a key business lesson from this early rock maverick. More on that in a moment.
Shannon—whose real name was Charles Westover—heard my LA rock band, The Band of Angels, at a small nightclub in the San Fernanco Valley in the early '70s and expressed an immediate interest in producing us.
In addition to his success as a recording artist (known for his piercing falsetto and highly original compositions), Shannon had produced hits for others ("Baby It's You" by Smith and "Gypsy Woman" by Brian Hyland), and had discovered Bob Seger a few years earlier. He was also the first American artist to recognize the Beatles' songwriting potential—after they had opened for him in London in 1963—and got his own version of the Beatles' "From Me to You" onto the US record charts long before they did.
So when Shannon dubbed us "a combination of the Rolling Stones and Everly Brothers" we took notice. But not enough notice, apparently, because we got busy and he got busy, and nothing came of it. (Come to think of it, that seemed to happen a lot in my music career at the time.)
