Come along, children
Now we're gonna have a little music
Like old times, like old times
Look now I'll start the melody on the organ

*Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
Oldie but a goodie
Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
That's just plain poppy-talk

Ooh-ooh, ooh
Ooh-ooh...

Yeah, yeah...

Ooh-ooh, ooh
Ooh-ooh...

Let me hear ya say, yo! (yo!)
Yo! (yo!), Yo! (yo!), Yo! (yo!)...
Yeah!

Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
Bop-dop-a-do-wop do-wop-bam-boom

Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
Bop-a-do-bop, bop-a-do-bop
Wop-bop-a-do-bop do-wop-bam-boom

Yeah, yeah...

Ooh-ooh, ooh
Ooh-ooh...
Let me hear ya say, yo! (yo!)
Yo! (yo!)...
Bop-dop-a-do-wop do-wop-bam-boom

*Repeat
