I, too, objected to ASHORE as a "way" to be washed. ASHORE is a place or a direction to be washed to. The crossword also included AEONS, which frequently appears in puzzles although I doubt that anyone really spells the word that way. It is always EON. Perhaps someone can aexplain the use of AEON. (See what I did there?)
"'70s Sonny & Cher label" was KAPP. The record label was founded in 1954 by David Kapp, whose brother Jack had started Decca Records twenty years earlier. Most of Sonny & Cher's hits, including I Got You Babe, were released by Atco. They had three hits on Kapp in 1971-72: All I Ever Need Is You, A Cowboy's Work Is Never Done and When You Say Love, which was adapted from a 1970 beer commercial, "When you say Budweiser, you've said it all." Thousands of old rock'n'roll songs have been used in commercials, many of them with the lyrics changed---remember YMCA becoming "P-E-P-S-I" and Viva Las Vegas becoming "Viva viagra"?---but there have been very few commercial jingles turned into songs. The most well-known example: "I'd like to buy the world a Coke" became a hit for the New Seekers, I'd Like To Teach The World To Sing.
