What was the best 45 single released by Queen?

Is there two-four songs that happened to be on the same single that you just love?

FBG / BR

WWRY (Fast) / LMEY (Live)

BC / SP

Notable mentions: Queen's First EP and SSOR / SWAFIB

And you?

I'll be cheeky and couple 2. Killer Queen / flick of the wrist and now I'm here / Lily of the valley. Bought both at the same time and thus followed my lifetime music experience. Playing and flipping these 4 eclectic songs on our Radiogram was beyond description. These guys are phenomenal. Knew they would be with me for life.

SSOR, my first Queen vinyl and it had this weird and wonderful B side!

Agreed. Reading about SWAFIB years before actually hearing it was fascinating. And then finally getting a copy was like woah

Hammer To Fall / Tear It Up

What a heavy metal single.

F / FF

just because I wanted to see what that looked written down

Bohemian Rhapsody / I'm In Love With My Car
You're My Best Friend / '39
Tie Your Mother Down / You And I
Queen's First EP
Too Much Love Will Kill You / WWRY & WATC
Let Me Live / FBG & BR

Play the Game/A Human Body

Liar / Doing All Right

Another One Bites The Dust / Dragon Attack

Radio Ga Ga / I Go Crazy

"The best" in terms of what?
I'm convinced that Champions/Rock You is the most glorious 45 containing two of THE MAIN rock/sports anthems of all time.

Agreed ^

Not sure what best means here, but the first Queen single I ever bought was bo rap with iilwmcar and I played both sides of that sucker to death.
I used to play the b sides of all my singles , though some b sides were truly dreadful and didnt get played often.
Excluding double a side singles for Queen I'd put bo rap top, tymd and you and I might be 2nd. I like it when the two songs are quite varied and show multiple sides of the band.

Parissienne walkways bw fanatical fascists by Gary Moore got a lot of b side plays.
