I can't believeAnd "Woman" has:
It's happened to me
I can't conceive
Of any more misery
I can't conceive, no"Woman" uses believe and conceive more as an internal rhyme where "Ask Me Why" uses them for a line-ending rhyme.
I can't believe you love me too
"Ask Me Why" was released as the b-side to the "Please Please Me" single on 11 January 1963, and "Woman" was released as the b-side of the "Leave Me Be" single on 16 October 1964. (Coincidentally, both songs were the b-side of each band's second single.) So, between the chronology and the Beatles' influence on Rod Argent (which he's mentioned multiple times), there might be a connection between these two songs. On the other hand, rhyming believe and conceive isn't too unusual, so it might just be a coincidence that both songs use them. At best, it's just a conjectured influence.
