May 12th, 1963: The Beatles appear on "Thank Your Lucky Stars" and show off their new logo! In the first photo, Lennon is wearing glasses at rehearsal, and Ringo's bass drum is still sporting the "beetle" Beatles logo. In the second one from the actual broadcast, new drums with the brand new "dropped T" logo, as designed by Ivor Arbiter.
The first Beatles "Beetle" logo
The old "beetle" Beatles logo kept it going, though. It was used quite a bit for their French releases (where they swapped the "the" for a "les"), and it was also featured a lot in the "Beatles Monthly Book" fan club magazine.
