Bill Bell joined the Sousa Band in 1921 and continued with the Band through 1923.
While with the Band, he was a soloist each of the three Summers at Willow Grove Park.
Below is an autographed pic of Bell in 1921 at Willow Grove with his Conn Raincatcher.

The solo Bell played was The Mighty Deep by Jude from 1898. Here are the four actual programs from Willow Grove showing Bell as soloist on the piece.




This Tuesday, I will be rehearsing with an area Summer Band and will play The Mighty Deep with them three times this July on my silver Conn Raincatcher from 1923.
While quite an easy piece to play with band, some of you might want to do it yourself— possibly in 2021-23— with a band to celebrate the 100th anniversary of Bell soloing with the Sousa Band. As far as we know, Bell only soloed with the Sousa Band at Willow Grove.
