The first Beatles song Bob Dylan heard on the radio

Both the Beatles and Bob Dylan were featured on the 2012 season opener for History Detectives.
What was the first Beatles song Bob Dylan heard on the radio?
Bonus: What line in the song did Bob Dylan misunderstand what the Beatles were actually singing?
The first Beatles song heard by Bob Dylan on the radio was “I Want To Hold Your Hand.” At the end of the middle eight, Dylan mistakenly thought the Beatles were singing “I get high” instead of “I can’t hide.” This impressed Dylan because he thought it was a drug reference. While there were no drug references in the early Beatles songs, that would soon change. For what it’s worth, as an eight-year-old first hearing the song, I also thought the Beatles were singing “I get high” until I saw the lyrics printed in a song book. I was too young to think of the line as a drug reference.
