its a blues song and the only lyrics i can remember are "boom boom boom boom"

It's probably "Boom Boom" originally done by John Lee Hooker and later covered by the Animals.

You'd be better off listening to these versions rather than the Blues Brothers. They're not really a very good example of blues singers.

"Boom Boom" – as mentioned in other answers the song is by John Lee Hooker; in the movie performed by John Lee Hooker (as "Street Slim"), vocals and guitar' Big Walter Horton (as "Tampa Pete"), harmonica. Pinetop Perkins (as "Luther Jackson") electric piano; Willie "Big Eyes" Smith, drums; Luther "Guitar Jr." Johnson, guitar; Calvin "Fuzz" Jones, bass. All of these guys are blues legends in their own right.

Yes, John Lee Hooker; and just FYI he was the man that Billy Gibbons and one or two of the other ZZ Top members had heard live in Houston one evening, and then the next morning they were in the studio recording their next album, Tres Hombres, released in 1973, and as the producer came in, he heard the band imitating John Lee Hooker, showing the other guys what he sounded like, his voice, joking with the lyrics and the "hmm hmm" bit; which is a John Lee Hooker staple, so later the producer made them make a record of the stuff they were doing and it became "LaGrange". Interesting, eh?

Boom Boom....John Lee Hooker, and that was him in the movie singing it too!

Hi,

To clarify, it is Johnny Lee Hooker singing the song in the movie and the song is "Boom Boom". I recommend his greatest hits highly, the one with the burgandy cover and him with a pipe and a hat, with "One Burbon One Scotch and One Beer" also (later covered well by George Thoroughgood). BEWARE, there are lots of BAD greatest hits out there (in the CD cut out piles) for him since he was around his the 40's. I bought a couple of them by mistake. Avoid the "Real Folk Blues" and other things that call themselves "Greatest Hits".

He was from Detroit originally and influenced tons of musicians with his unique clawing/crawling rhythm guitar playing and stomping foot (ZZTop use "How how how how"...from "Boom Boom" in their songs). His later-in-life/comeback CD, "The Healer" won a grammy with his duets with Bonnie Raitt and Carlos Santana (before Santana's comeback CD lol). His favorite guitar model was the Epiphone Sheraton with his best work being electric. He played with the Rolling Stones on occasion too.

To the people hating on the Blues Brothers movie, get a clue, Jake and Elwood, even as characters, are just as faithful disciples as Clapton et al. Just because you don't play guitar doesn't mean you don't get the blues. Steve Cropper and Duck Dunn in your backing band with Matt "Guitar" Murphy...(not to mention...Ray Charles, Aretha Franklin....James Brown) that's respect from the blues community just by playing with those guys.

Bottom line, Hooker's gone, but I love his music and I'm glad you found it for your own listening pleasure. Enjoy.

Good luck...and peace.

Probably "Boom, Boom" by John Lee Hooker.
