The Helen Way Singers sang on the Darin tune (1) in 1958 (1).  Bobby Darin’s song was written in 1958 (1).  It must be “Early” (1), (2), (3).  “Early In The Morning” could not be recorded in February or March (2) nor on May 27, 1957 (2) so it must be June 19, 1958 (2). “Think It Over” was recorded in 1958 (1) so it must be February 14, 1958 (2), (3).  “Not Fade Away” was not the “worst song” (2) and it was not recorded in 1958 (2).  The Picks didn’t sing background on it (5).  It could not be recorded on February 24-25, 1957 (2).  So it must be May 27, 1958 and Buddy sang background on it (4) and Jerry played a cardboard box on it (4).  The “worst song” could not be recorded in 1958, nor on May 27, 1958 (2), nor March 12, 1957 (5) so it must be recorded on February 24-25, 1957 and the Tolletts sang on it. The Roses sang on the song with piano lead (3), which was not recorded in 1957 (4), (5) and fact “worst song” was recorded on February 24-25, 1957 (from deduction above). It must be “Think It Over” recorded on February 14. (All clues)  The Picks sang on “Maybe Baby” (3).  Buddy sang background on the song recorded on May 27, 1957and it had the “cardboard box” drums on it (4).  Buddy’s mother gave him the title to the song recorded on March 12, 1957and the Tolletts didn’t sing on it (5).  The Picks sang on it, so it must be  “Maybe Baby”, which had to be recorded on March 12, 1957. (3) (5) “That’ll Be The Day” wasn’t recorded in 1958 (2) or on May 27 (2) or on March 12 (5) so it must be February 24-25, 1957.
