In the 1975-76 season, Sanderson scored his 32nd career short-handed goal to surpass Toronto Maple Leafs center Dave Keon as the all-time league leader.

Nearly half a century after his last appearance with Boston, Sanderson still owns the Bruins team record for most career shorthanded goals (six) in the playoffs, a mark that he shares with Ed Westfall, his longtime teammate.

[5] In his early youth, Sanderson took to hockey, skating countless hours on a scaled-down version of an NHL rink, which his father built and maintained while his mother served hot chocolate during breaks in the action.

The rink spanned two backyards of small cookie-cutter houses on lots provided at modest prices to servicemen such as Harold upon their return home.

Instead, head coach Harry Sinden had a different vision for him, one as a valuable multi-purpose center who neutralized the top center men in the league, dominated at the face-off dot, helped kill penalties at a high rate, unnerved opponents with physical if not chippy play and contributed at the offensive end on a regular basis.

[13] After their series victory over the Rangers followed by a sweep of the Chicago Blackhawks in the 1969–70 playoffs, the Bruins faced the St. Louis Blues in the Stanley Cup Finals.

The defenseman fired a short wrist shot past goaltender Glenn Hall, clinching the Bruins' first Stanley Cup in 29 years.

It was widely speculated that it had hoped to prod Sanderson to bolt the team and void his lucrative deal but his contract was bought out for $800,000 after the season.

[16] Sanderson also received publicity for his numerous female companions and lavish ways, which included a Rolls-Royce car and circular bed.

[17] Named by Cosmopolitan as one of the sexiest men in America, he was the subject of gossip columns, and a frequent guest on television talk shows.

In June, 1969, Namath called to gauge Sanderson's financial interest in a bar similar to Bachelors III, which the quarterback had owned on New York City’s Upper East Side before concerned league commissioner Pete Rozelle ordered him to cut ties or retire from football, only this one in Boston.

Not one to turn down the spotlight and its many perks, Sanderson opened Bachelors III along with co-partners Joe Cimino and Jim Colclough, a one-time Boston Patriots wide receiver.

"That's how I learned how to pick up the tab," Sanderson recalled in his book Crossing The Line: The Outrageous Story of a Hockey Original.

Named after the Great Gatsby’s lover in the F. Scott Fitzgerald classic, Daisy Buchanan's opened its doors in September 1970 at the corner of Newbury and Fairfield Streets.

Bruins teammates Bobby Orr, Phil Esposito, Gerry Cheevers and Eddie Johnston were regulars there, but the omnipresent Sanderson served as the main attraction and promoter, usually behind the bar, cigarette in mouth and drink(s) in hand.

Negative publicity over some of the club's less-than-reputable patrons led to concerns and eventually convinced Sanderson to relinquish his interests in what had gone from a financial "goldmine" to a money pit.

In the pre-season, he was involved in a brawl at a local strip club that left him in a hospital, where tests showed an extremely high level of alcohol as well as evidence of cocaine, sleeping pills, Seconal and Valium in his system[citation needed].

His partying lifestyle caught up with him by the time his career ended and he was found sleeping in an inebriated state on a bench in Central Park.

[25] His second autobiography, Crossing the Line: The Outrageous Story of a Hockey Original, written with Kevin Shea, was released in October 2012.
