What was the UK B-side of The Who's 1968 single 'Magic Bus'?

The UK B-side of The Who’s 1968 single “Magic Bus” was “Dr. Jekyll and Mr. Hyde.”

The song was written by bassist John Entwistle and recorded in January 1968 at IBC Studios in London. Its horror-themed lyrics and menacing arrangement were inspired by Robert Louis Stevenson’s famous divided-character story, while the subject was also closely connected to drummer Keith Moon’s drinking problems.

The single had different B-sides in different markets, which creates the main source of confusion. The United States used “Someone’s Coming” as the B-side to “Magic Bus,” whereas the United Kingdom paired the release with “Dr. Jekyll and Mr. Hyde.”

There were also different recordings of Entwistle’s song. The UK version runs longer than the US version and features a more prominent guitar part along with additional spooky vocal effects. That regional distinction makes the stored answer specifically correct for the UK pressing.
