BUT WHAT ABOUT STRAWBERRY ALARM CLOCK?: if you've not heard:

It's all a part of a rare collection of some 500 original tapes by the British rock legends that police announced Saturday had been recovered three decades after their mysterious disappearance. Two people were arrested in London and three others in the Netherlands.

Police said the reel-to-reel tapes, believed to have been stolen in the 1970s and which had become something of a Holy Grail for record industry investigators, were retrieved following a year-long investigation that began when they were offered to the EMI record company for $430,000.

Beatles historians said the tapes were made during what was known as the group's "Get Back" sessions while they were working on the album that became "Let It Be."

The music was described as "priceless" and "unique," on tapes that contained hundreds of hours of rehearsals, dialogue and alternative versions of songs released elsewhere. The music is reported to include dozens of entire songs, as well as snippets of tracks that the Beatles attempt and then abandon during rehearsals.

"As well as new songs," one music expert reportedly described, "the band ran through early tracks, for old time's sake," as they neared the end of their collaboration.

But what may trigger the fascination of many Beatles aficionados even this many years after the band's break-up - and the deaths of two of its members, John Lennon and George Harrison - is that the tapes contain tracks that have never before been released.
