The Mick Fleetwood Island Rumours Band will make a rare public appearance when they perform at a special benefit for Seabury Hall on Oct. 19. The band features acclaimed former New York session guitarist Joe Caro, Eric Gilliom and Gretchen Rhodes on vocals, Mark Johnstone on keyboards, Lenny Castellanos on bass, and, of course, the British legend on drums.

With Caro serving as music arranger, the Seabury show will likely feature the Rumours Band playing a range of Fleetwood Mac classics – “The Chain,” “Go Your Own Way,” “World Turning,” “Rattlesnake Shake,” “Dreams,” “Black Magic Woman,” and “Rhiannon.”

Based on Maui after years in New York, Caro’s extensive credits include working with Aretha Franklin, Chaka Khan, Crosby, Stills and Nash, Carly Simon, and the Eagles. His most recent album, “Every Dog Has His Day,” featured new arrangements of Dylan’s “Highway 61 Revisited” and Hendrix’s “Fire.”

“He’s awesome,” says Lenny Castellanos about Caro. “He is one of those true New Yorkers.”

Playing with Fleetwood for around 20 years, the Kula based bassist was nominated for a Grammy Award for playing on the live Fleetwood Blues Band album “Blue Again!”

“Playing with Mick, he’s amazing,” he says. “You lock into him and it’s a whole different thing.”

They first teamed in 2007 for the launch of the Island Rumours Band. “I went to a jam session,” he recalls. “It was really fun, and he called me back, and said, ‘Lenny, that was really nice.

Thanks for playing some hot bass.’ Then somebody called me to do a jam again, and it turned out to be one of those things where he’s trying to get the band together, the blues band, and I was already ready for it. I knew all the music. I loved songs like ‘Oh Well’.”

Castellanos reports he loved touring with Fleetwood, and especially enjoyed their time in England. “It was the best,” he recalls. “He called us lads, me and Mark Johnstone. He treated us so well. It was a great experience, I’ll never forget.”

There’s such a love for blues in Britain and early Fleetwood Mac fans relished hearing so many classics played by Mick and the lads. “We were doing all this stuff that they did when they first started the band, and people were so amazed. The feeling we got from all those people, I’ve never been in a situation where everybody’s, whoa. It was great.”

Other memorable moments for him included the historic show at the MACC with Christine McVie in 2013, after McVie left Fleetwood Mac to retire in England in 1998, and a trip to Maui helped coax her back into performing on stage again.

Besides playing on the Grammy nominated “Blue Again!” in 2010, the Maui bassist was also featured on the album “Mick Fleetwood Blues Band, Featuring Rick Vito Live at the Belly Up,” released in 2016. A Jambands review noted, “this is a stellar album that will baffle fans of the contemporary Fleetwood Mac and bedazzle fans of the original incarnation.”

One wonders if he ever connected with Fleetwood Mac’s legendary bassist John McVie. Yes, he did.

“I love him,” says Castellanos. “When we went to the Diamond Head gig we had with Earth, Wind and Fire, they had a place to hang out and he was sitting there. I told him you’re one of my favorite bassists. Back in the day, I was listening to British blues, and he just was one of the best bass players anywhere in Europe.”

Did McVie ever mention anything about the Maui bassist’s playing? “He told Mick, ‘you know, he’s really good.’ But I don’t know if I believe it.”

The Seabury benefit will also feature multi-Nā Hōkū Hanohano Award winning guitarist Jeff Peterson, Hōkūwinning musician Kamalei Kawa’a, who performed on NBC’s “The Voice,” and DJ O’Soulmain.

Peterson just released the new recording “Slack Key for the Holidays,” which includes his solo guitar interpretations of gems like “Deck The Halls,” “Ave Maria/Hallelujah,” “O Holy Night,” and “God Rest Ye Merry Gentlemen.”

The Seabury Pa’ina is presented on Oct. 19, between 5 and 10 p.m. More info is available at www.seaburyhall.org/about/seabury-paina.
