Famous quotes containing the words lead and/or free:

    A woman’s a two-face
    A worrisome thing who’ll lead ya t’ sing the blues in the night.
    Johnny Mercer (1909–1976)

    When we our betters see bearing our woes,
    We scarcely think our miseries our foes.
    Who alone suffers, suffers most i’ the mind,
    Leaving free things and happy shows behind.
    But then the mind much sufferance doth o’er skip,
    When grief hath mates, and bearing fellowship.
    William Shakespeare (1564–1616)
