Herb Alpert’s Rise featured this low-key album track on side two.  Penned by singer/songwriter Bill Withers, “Love Is” appears on his album ‘Bout Love.  Long out of print, it has recently been made available on CD by way of the Complete Sussex & Columbia Album Masters box set, containing mini-LP versions of all of Wither’s albums, for about the cost of two single CDs.  Essential!
