Brian Evans, the Haverhill-bred crooner whose song paying tribute to Fenway Park has been viewed over 3.7 million times on YouTube, is back with another Red Sox-related project. And, like the song, this one’s a little odd. Evans sent out a press release this week announcing plans to write a book about the making of the video, and what it was like dealing with Red Sox management. The book, which Evans says will give fans a behind-the-scenes glimpse of the Sox brass, will be titled “The Green Monsters — A Fan’s Perspective of Red Sox Management.” (Not to be confused with Seth Mnookin’s “Feeding the Monster: How Money, Smarts, and Nerve Took a Team to the Top.”) Is Evans calling Sox owners John Henry and Tom Werner “Green Monsters”? He couldn’t be reached Thursday, so we have to rely on the press release, which states, “This book will bring insight fans have never had before that will be supported by documentation.” Huh? If you haven’t seen it yet, Evans’s bizarre video tribute to Fenway, called “At Fenway,” is worth a look. Shot at the ballpark, the video shows Evans wandering around in a tuxedo while singing a big-band tune. Car dealer Ernie Boch Jr. and “Star Trek” actor William Shatner make cameos. As we’ve noted before, Evans is certainly a colorful character. In his 20s, he spent time in jail for impersonating, and charging plane tickets to, “American Top 40” radio host Casey Kasem. And in 1990, he sang the national anthem at Fenway and then was promptly led away in handcuffs. Boston police told the Globe at the time that Andover police had a warrant for Evans, alleging he’d defrauded the Sheraton Rolling Green. Asked Thursday about the team’s current relationship with Evans, the folks at Fenway sent us this statement: “We appreciate that Mr. Evans, like other fans, expressed his love for Fenway Park in song. Although it is his song entirely, we have lent some support, as we have done for others.” They had no comment on the book.
