Beatles Without George Martin?

Martin was/is a talented guy who helped catalyze and more importantly successfully capture (in recordings)in a marketable way the combined talents of the individual Beatles.

It was a unique combination of talent, collaboration and synergy that obviously produced outstanding and most likely timeless results.

Martin was a key member of that particular highly talented and successful team. He has done lots of other good work as well, but nothing as significant culturally as his early work as an innovator with the Beatles.

"None of them were nearly successful as the band itself".

That's because, while it lasted, the talents of each individual Beatle, including Martin, complemented the others almost perfectly.

Take any of them individually, and while still uniquely gifted in different ways, there is not the overall balance and synergy that characterized the Beatles.

Yes, I vote for Ed Sullivan as the one who ushered in the British Invasion!
