Unlike the
1962–1966 collection, the Blue Album was largely the same in the U.S. and the UK, although there were some variations. The U.S. edition had "
Strawberry Fields Forever" in its original 1966 stereo mix, while "
Penny Lane" and "
Hello, Goodbye" were presented in mono, and "I Am the Walrus" with a four-beat electric piano introduction; the UK version had the more common six-beat beginning. The albums had several other variants and anomalies. "
Get Back" was described as the album version in the U.S. liner notes, although it was in fact the single version. In both countries, "
Hey Jude" was around nine seconds shorter than it had been on the original single, although the full length was restored for the 1993 compact disc edition. The original vinyl version faded in during the crowd noise at the beginning of "
A Day in the Life". The fade in was different on both the UK and U.S. versions. The original compact disc edition, meanwhile, featured a clean version previously heard on the
Imagine: John Lennon soundtrack album in 1988. On the Spanish edition, "
One After 909" replaced "
The Ballad of John and Yoko", a song that had been banned from the airwaves shortly after being released as a single in 1969, for its allusions to "Christ" and "Gibraltar" in the lyrics. == Release variations ==
