Music producer Dalton Browne suffered a massive heart attack on Saturday, and needs blood as he will have to undergo a quadruple bypass surgery this weekend.

“He had a massive heart attack on Saturday,” Cleveland Browne, Dalton’s brother and one half of the legendary production duo, Steely & Clevie, to Loop News during an interview.

“He has to undergo a quadruple bypass surgery and that requires a large amount of blood. The appeal for blood is urgent, because the family supply is simply not enough, so we’ve been reaching out to the music industry and the public. His children are in the US and have not been able to come yet because of the protocol restrictions to do a test in order to get on a plane. So we need people to give blood for Dalton, and do it in his name and send the message to a number on the flyer,” Browne said.

Dalton Browne, 64, is the second of five Browne brothers, all of whom are musicians. Glen (bass), Noel (keyboards), Cleveland (keyboards) and guitarist Danny are his siblings.

They were once known as The Browne Bunch which formed in the early 1970’s.
