I almost forgot to mention...

...what a coincidence it was that Johnny Otis and Etta James died in the same week.

From Mr. Otis's obit in the Times Thursday (my emphasis):

With a keen ear for talent, he helped steer a long list of performers to stardom, among them Etta James, Jackie Wilson, Esther Phillips and Big Mama Thornton — whose hit recording of “Hound Dog,” made in 1952, four years before Elvis Presley’s, was produced by Mr. Otis and featured him on drums.

At Mr. Otis’s induction into the Rock and Roll Hall of Fame in 1994, Ms. James referred to him as her “guru.” (He received similar honors from the Rhythm & Blues Foundation and the Blues Foundation.)

And from Ms. James's obit today:

She began singing at the St. Paul Baptist Church in Los Angeles at 5 and turned to secular music as a teenager, forming a vocal group with two friends. She was 15 when she made her first record, “Roll With Me Henry,” which set her own lyrics to the tune of Hank Ballard and the Midnighters’ recent hit “Work With Me Annie.” When some disc jockeys complained that the title was too suggestive, it was changed to “The Wallflower,” although the record itself was not.

“The Wallflower” rose to No. 2 on the rhythm-and-blues charts in 1954. As was often the case in those days with records by black performers, a toned-down version was soon recorded by a white singer and found a wider audience: Georgia Gibbs’s version, with the title and lyric changed to “Dance With Me, Henry,” was a No. 1 pop hit in 1955. (Its success was not entirely bad news for Ms. James. She shared the songwriting royalties with Mr. Ballard and the bandleader and talent scout Johnny Otis, who had arranged for her recording session. Mr. Otis died on Tuesday.)
