Is this it? Lari White - High http://www.metrolyrics.com/high-lyrics-lari-white.html Here's a "guy" version and the lyrics: I Must Have Been High http://www.paulthorn.com/store/cd/clips/high_lo.mp3 (short part of refrain) Lyrics from http://www.edcahoon.com/Lyrics2.html Love, righteous and real A dream I could touch Trust I could feel I had it all and I threw it away With some stupid move I wish I could take back today Was I lost, was I blind Baby I couldn't see What losing you would do to me baby I must have been high To let you walk away To let you say goodbye I must have high Darling I'll never know How could I let you go? I must have been high Stoned out of my mind Time has opened my eyes These empty arms Have made my heart wise I'll never find A better lover and friend I'm ashamed to admit What a fool I have been And I know I've got no right To be begging you to come back to me I can only plead insanity Baby mercy baby I must have been high To let you walk away To let you say goodbye I must have high Darling I'll never know How could I let you go? I must have been high I must have been high To let you walk away To let you say goodbye I must have high Darling I'll never know How could I let you go? I must have been high

You can often search for songs by partial lyrics on many lyrics sites on the internet. I've often found songs that I could only remember a partial phrase or tune this way. Might take a little patience, but it can be done.
