(CNN) — Patti LaBelle is very fond of her Tupperware. The singer, who loves to cook (and sells her own line of “Patti Pies”), shared an interesting tale on Sherri Shepherd’s daytime talk show. LaBelle explained that back before Elton John was famous and he was going by his birth name, Reginald Dwight, he was playing piano for her with his band Bluesology when she performed in the UK.
