My wife was involved in touring with Dan following his unexpected top ten hit I Can Dream About You circa 84 - 85.
MCA hastily put together a band to support live dates, Dan made two more videos for MTV which of course was in it's heyday... and toured in Europe and a few dates in the US to support his solo album.
At that stage Dan was not actively pursuing a solo career. He had formed a songwriting partnership with a fellow named Charlie Midnight, which was going well, and was probably more lucrative and less of a headache than going solo. Also, his dance hits and his years with Edgar Winter created confusion in his fan base,.. was his disco? metal? etc..... Labels wanted to pigeonhole you and Dan, having spent years in the business was in his mid 30s and I doubt wanted to play any games. Gay male performers were still under the radar in 1984, despite Elton, Boy George, .... labels really wanted none of that.
Dan was phenomenally gifted, and really could do it all, and tailoring a song for another artist was a gift few in the music biz could match.
The few times I was with Dan socially, he was a complete gentleman. Generous to a fault, comp tickets to see Chaka Kahn in London, picking up the dinner tab...having us out to his home in Connecticut .NO substance abuse issues were ever spoken of.
He was going with a fellow who was either in law or finance. He was not introduced as a boyfriend or partner.. it was not necessary. nothing was closeted about Dan, he was completely comfortable in his own skin, but sexuality was your own business and in a mixed gathering , just not talked about. He didn't have boys hanging around, any cliches you might conjure up about a gay 80s rocker. I think in his heart, he was a child of the 50s with a very strong work ethic. He was very kind to his younger sister, who I believed managed his calendar.
Neither follow up singles charted well enough to put out another solo album,... that is my hunch anyway. Dan quickly had success penning Jame Brown Living in America and so he was off in that direction working with other acts.
My wife did not keep up with him, as he used studio musicians and I don't think he ever performed as a live rock act again....
My takeaway, Dan was generous to a fault, driven to succeed, but happy to share success with others. If he had lived, he would have been out and a big part of the emerging gay movement in the music biz.
