When there's a fire in your heart Break the glass sound the alarm Call on me I'll be there Instant service, speedy, fast I was your first I'll be your last No matter who you have in between. When there's a fire in your heart Break the glass sound the alarm When she's not all she seems Instant service, speedy, fast I was your first I'll be your last No matter who you have in between. There's been hearts spells In close spells ever since we met I've seen your small fires, your big fires But I won't give up yet. Oh, someday you'll yearn cause your heart's gonna burn For that old familiar glow You'll be burned out on, smoke out And come back to me I know. [Instrumental] Every thrill that you blaze Makes me stay up closer behind While you've been datin' I've been waitin' Just hurtin' all the time. Your new flames was older and all will grow colder For mine was higher and high So I'm hanging on you see 'Cause you'll come running back to me 'Cause I'm fightin' fire with with fire. When there's a fire in your heart Break the glass sound the alarm Call on me I'll be there Instant service, speedy, fast I was your first I'll be your last No matter who you have in between. When there's a fire in your heart Break the glass sound the alarm When she's not all she seems Instant service, speedy, fast I was your first I'll be your last No matter who you have in between When there's a fire in your heart Break the glass sound the alarm Call on me I'll be there
