Telephone Blues lyrics

I couldn't sleep last night. I was sitting by my telephone. All the time a-wastin', All the love you've never shown. But someday, someday darling, You will realize I'm alone. The last time I saw you, You promised me you would call. But time is running out, babe; No call at all. My life is so lonely Standing by my telephone. But someday, someday darling, You will realize I'm alone.
