After the breakup of the Beatles in 1971, Paul began teaching Linda to play keyboards, and included her in the lineup for his new band, Wings. Although Linda was shunned by music critics for her amateur singing and playing skills, Wings garnered several Grammy Awards for their music. Linda developed her musical talent through the years, even writing and recording her own music. Her album, Wide Prairie was released posthumously in 1998.
Linda introduced her husband to vegetarianism and popularized a meatless diet through her best-selling cookbooks and line of frozen vegetarian meals. Additionally, Linda was a vocal advocate for animal rights.
When breast cancer claimed Linda's life in 1998, Paul suggested that fans remember her by donating to breast cancer research, "or the best tribute�go veggie".
