The Brendan Behan Pub isn't the greatest place in Boston to catch a ballgame. The Jamaica Plain watering hole is little more than a single room with booths crammed to one side, the bar taking up the other. Patrons jostle each other to get a view of the single projection screen on the far wall. And tonight, during Game Four of the World Series, the women's restroom was out of order.

But its patrons wouldn't watch the Sox win the Series in any other bar.

"You can go to places with better TVs," said Carrie Baldwin, who has been coming to the Behan since at least 2003, "but you can't beat the atmosphere."

Russ Dial is part of that atmosphere. An energetic man with blond dreadlocks and piercing blue eyes, Dial has been a part of Sox games at the Behan since 1992. The shuffling dance he does between innings, when he distributes hugs and high-fives along the bar, might be the way he gets closest to his fellow patrons. But it's his songs that set him apart.

Dial and his friend Dan McLeod have a song for every member of the Red Sox postseason roster. Set to the tune of classic rock hits, every Sox at-bat shown at the Behan comes with its own theme music.

Dustin Pedroia gets the Kinks. "Dustin Pedroia will destroy-ya," Dial, McLeod, and a small cadre of supporters intone when he steps into the box.

Julio Lugo's song is a favorite of Dial's. Set to the tune of the Eagles' "Witchy Woman," it goes, "Oh, oh. Julio Lugo. See how hard he tries."

Dial and McLeod's routine might puzzle some patrons. "He belongs to another world, I think," said Bobby Acosta, a native of the Dominican Republic who watched the Sox at the Behan on Tuesdays, Fridays and Saturdays during the entire 2007 season.

But, when Manny Ramirez came to bat in the fourth inning tonight, the influence of Dial and McLeod could be heard loud and clear.

"Oh, oh here he comes. Watch out boy, he'll chew you up. Oh, oh here he comes: he's a Manny!" came the call, set to the tune of Hall and Oates's "Maneater," from a swath of voices, beginning with the regulars in the booths against the wall and ending with the newcomers in the back.

Ramirez flied out, but that didn't stop the Behan from erupting in the refrain of "Manny, Manny, you're so fine!" as he returned to the dugout.

All of the tunes are created on the spot at the Behan. And, with new players being added to the Sox roster every season, the crowd has to give Dial and McLeod a hand.

"Someone else made up 'Ellsbury Fields Forever,'" Dial admitted.

As players come and go, their songs disappear from memory. But what doesn't disappear is the enthusiasm of the Behan's patrons for this unique expression of loyalty.

"At the first playoff game, people hear it, and they kind of get into it. And then you hear people sing it back to you, and you're kind of like, 'Okay!'" said McLeod.

During the bottom of the ninth, the Behan's crowd seemed to double in size with each Rockies out. By the time Papelbon sealed the deal, you could practically hear the building quake as the patrons erupted in triumph. The bartenders doused the crowd with champagne as several women and, finally, Dial himself took turns surfing the crowd's shoulders. Bob Marley's "Jammin'" played in the background.

Amidst the revelry, McLeod, ordinarily gregarious, only had three words to say.

"Fuckin' A, man."
