D&D5e subclasses are very versatile. Even with a party of four you have plenty of options. You can make a Bard All-stars party if you want to.
Githyank/MountainDwarf - College of Valor bard (Outlander) - Main tank [OPT: 1 level of Fighter]
Lightfoot halfling - College of swords (Urchin) -Scout, striker and trap-lock disabler [OPT: 2 levels of rogue]
Tiefling - College of eloquence (Guild artisan) - The face of the group and main healer. [OPT: 1 level of Life Cleric]
Half-elf - College of Lore bard (Sage) - Skillmonkey and offensive/control caster.
Funny you should mention it, my DM decided that tomorrow we are taking a night off from the main campaign to do a one-off: we will all being playing bards who are coming together to preform for a charity benefit concert for a city that our main party may or may not have inadvertently destroyed a few sessions back.
The Rock Gnome Bard from the College of Glamour, Diesel Axlstrings, is riding out again.
