Just use noise and swing march. Casting the dances around level 90 consumes too many SP. You have to take robes for the 10% pot gain and put MP blues and INT blues on the equipment.
The same applies for full str clerics, the spells start to consume so much sp that you can't be a cleric in a party excepted if a full int bard buffs the MP up. For a STR bard, he has to cast mana recovery on him, cast on one player, recast on him, cast on second plyaer etc.... All he can do is using tons of the highest level MP pots.
My advise is to look very carefylly at the needed MP for casting a spell, at the end you need more MP than you have basically. So keep an eye on that.
