Lyrics: Last night I was blown away I said a million things I'd never say I was knocked right down, it got to me Gonna get me some of your chemistry You want me to promise you That everything is true I won't make promises that I can't keep I won't make promises that I don't mean I'll even mean the things I tell you in my sleep, yeah I won't make promises babe, that I can't keep Oh my my, I lost control I told you everything, I said it all You came right out and said to me "Gonna get me some of your honesty" You want me to promise you That everything is true I won't make promises that I can't keep I won't make promises that I don't mean I'll even mean the things I tell you in my sleep, yeah I won't make promises babe, that I can't keep You want me to promise you That everything is true I won't make promises that I can't keep I won't make promises that I don't mean I'll even mean the things I whisper in my sleep Oh, let me tell you I won't say a single thing darling, that you can't believe You gotta believe me I won't make promises that I can't keep Oh baby believe me now I won't make promises that I don't mean Oh why won't you believe me now I'll even mean the things I whisper in my sleep, yeah I won't make promises that I can't keep Baby, you gotta believe me
