*Verse 1 (Jason)

If I had my wand
I would Sectumsempra

If I had the chance
I'd kill you now

Why'd I let you live
Mercy clouds my vision

But I see you now
On Marauder's Map

*Chorus (Group)

I solemnly swear that I'm up to no good (Luke)
Mischief managed

I solemnly swear that I'm up to no good (Jason)
Mischief managed

I solemnly swear that I'm up to no good (Aaron)
Mischief managed

I solemnly swear that I'm up to no good (Gang)
Mischief managed

*Verse 2 (Aaron)

I see Wormtail now
I see his pawprint coming
The trap is set
To catch that rat

Cruciatus curse
I will make you suffer
Aveda Kedavra's
Too good for you

*Chorus (Group)

I solemnly swear that I'm up to no good (Luke)
Mischief managed

I solemnly swear that I'm up to no good (Jason)
Mischief managed

I solemnly swear that I'm up to no good (Aaron)
Mischief managed

I solemnly swear that I'm up to no good (Gang)
Mischief managed

Aveda Kedavra's
Too good for you

*Verse 3 (Luke)(Jason and Aaron whispers)

Cruciatus, Sectumsempra, the killing curse
Cruciatus, Sectumsempra, the killing curse

Victim of my spells (Cruciatus, Sectumsempra, the
Killing curse)
I can see you struggling (Cruciatus, Sectumsempra,...)
Say goodbye

Aveda Kedavra!

*Chorus (Group)

I solemnly swear that I'm up to no good (Luke)
Mischief managed

I solemnly swear that I'm up to no good (Jason)
Mischief managed

I solemnly swear that I'm up to no good (Aaron)
Mischief managed

I solemnly swear that I'm up to no good (Gang)
Mischief managed

I solemnly swear that I'm up to no good (Luke)
I can see you struggling

I solemnly swear that I'm up to no good (Jason)
I'd kill you now

I solemnly swear that I'm up to no good (Aaron)
I will make you suffer

I solemnly swear that I'm up to no good (Gang)
On marauder's map

Mischief managed
Mischief managed
Mischief managed
I solemnly swear that I'm up to no good
