Call me, Beep me

Doesn't matter where, (doesn't matter where,)
Doesn't matter when, (doesn't matter when,)
I will always be there, (I will always be there,)
Until the very end, (until the very end.)

Call me, (call me,)
Beep me, (beep me,)
Call me, beep me
If you wanna reach me.
Call me, beep me if you wanna reach me!
