Adam Schlesinger, from the US power pop band Fountains of Wayne, has died aged 52 in a New York hospital, his family lawyer has confirmed.
He had been receiving treatment for Covid-19, with the use of a ventilator.
The bass player co-wrote the band’s 2003 hit, Stacy’s Mom – an ode to unrequited teenage lust, which starred model Rachel Hunter in the video.
He went on to win Emmy and Grammy awards for his soundtrack work on Crazy Ex Girlfriend, and A Colbert Christmas.
Chris Carrabba, from the band Dashboard Confessional, confirmed his death.
“I am grasping for the right words” he tweeted. “My dear friend Adam Schlesinger has passed away from COVID-19.”
He added: “I knew him best as a mentor, and a friend. We must take this seriously. People are sick and dying. It is hard to stay locked indoors but lives will be saved. Take care of each other. Rest In Peace, my dear friend.”
