Kenny Gamble (search), half of the songwriting duo that wrote a slew of 1970s hits, and R&B singer Bunny Sigler (search) have written a song to help raise money for Alex's Lemonade Stand (search), a charity benefiting cancer research.

The song, "Alex's Lemonade," details the life of Alex Scott, a girl from Wynnewood who was 8 when she died last August after fighting an aggressive form of childhood cancer almost since birth.

Alex had come up with the idea of selling lemonade at a stand outside her home to raise money for cancer hospitals. Her story made national news and she inspired hundreds of lemonade stands across the nation.

Gamble and Leon Huff were the songwriters behind the Sound of Philadelphia, and wrote the hits "Love Train," "For the Love of Money," "If You Don't Know Me by Now" and "Me and Mrs. Jones."

"Gamble and I created this song to help spread the word about Alex's inspiring life, her unique situation and her incredible determination," Sigler said.

The song costs $10 and is available at several Web sites including http://www.alexslemonade.com.

Alex's Lemonade Stand says it has donated over $1 million to pediatric cancer care centers across the country.
