We end today with letters. The letters many of you Beatles fans will probably send us about the music you're about to hear. Beatle purists will say that no one should perform the band's music but the Beatles themselves.

But think Earth Wind and Fire's cover of "Got to Get You Into My Life."

Or Joe Cocker's "A Little Help from My Friends."

It IS possible, Beatlemaniacs, that some artists can pull off Beatles' tunes...maybe even own them in a way the Beatles didn't.

Yes, there, that notion is finally out in the open.

Discuss among yourselves whilst we survey the latest entry in Beatles covers.

This one is a cover of an entire Beatles album.

This is the Easy Star All Stars, a mostly Jamaican reggae super-group that has made a living out of reinterpreting concept albums in reggae and dub.

They've already taken on Pink Floyd in "Dub Side of the Moon," and they covered Radiohead's "OK Radio" as Radiodread.

But doing an album called "Sgt. Pepper's Lonely Hearts Dub Band" is not only going into sacred Beatles territory.

It's going under the hood of the original concept album.

The good news is the concept remains in tact, even though Beatles fans might shrug and say, mneh, I'd rather listen to the original.

But first, check this out.

Kirsty Rock is not Jamaican.

She's a vocalist from Vermont who is billed as the "Queen of Dub."

Rock is known for skillfully delving into both Beatles tunes and Jamaican styles.

This is her appropriately ska rendition of "She's Leaving Home."

One of the other standout tracks is also not performed by a Jamaican, but by Matisyahu, a New York Hasidic Jew who plays dub.

He hit the reggae scene big time a couple of years ago.

And his familiarity with Yiddish major-minor scales makes him the ideal messenger for the mystical and Indian-inspired "Within You Without You."

The most surprising thing about Sgt. Pepper's Lonely Hearts Dub Band is how straight ahead many of these artists spin these songs.

They don't do complex acrobatics to make them sound overly reggae and dub.

It helps that the drug culture of Sgt. Pepper translates easily between Abbey Road and Trenchtown.

There are occasional lyrical substitutions.

But at the end of the album, you walk away with the same smile you had the first time you heard the real thing.

After all, they've been going in and out of style, but they're guaranteed to raise a smile.
