In American English, a gym bag is a large bag made of cloth or leather typically with a rectangular base and a zippered opening at the top. Two handles enable the bag to be carried, and a (usually removable) strap lets the user support the bag on the shoulders.
In British English, a holdall (or occasionally hold-all) may be a similar bag but may often have wheels and possibly a telescopic handle. The term covers a wide variety of types of bag.
A holdall is often used in place of a suitcase or for carrying sports equipment, and has the advantage over most suitcases of being compressible when empty.
A 'hold-all' is also used to carry bedding and blankets etc. Students, enrolled in boarding schools in India, are issued a 'hold-all' to carry their blankets, quilts and clothes. It is a flat, rectangular, canvas bag, when unravelled. Once filled, it is rolled like a sleeping bag and held together with straps.
Hello Dolly, well hello Dolly,
It's so nice to have you back where you belong.
You're looking swell, Dolly, we can tell, Dolly,
You're still glowing, you're still crowing, you're still going strong.
We feel the room swaying 'cause the band's playing
One of your old favorite songs from way back when,
Take a rap, fellows, find her an empty lap, fellows,
Dolly'll never go away, Dolly'll never go away...
(instrumental by Louie Armstrong playing his saxophone)
Hello Sax(Satch not Sax), this is Francis, Louie,
It's so nice to see you back where you belong,
You're back on top, Louie, never stop, Louie,
You're still singing, you're still swinging, you're still going strong,
You get the room swaying when you start in playing
One of your great songs, your songs from way back when,
Blow your horn, Louie, sing up a great big storm, Louie,
Promise you won't go away, promise you won't go away,
Promise you won't go away again.
