Unraced as a juvenile, she had just one outing last season, finishing two lengths runner-up behind Nightime at Cork in April.
Nightime, of course, went on to land the Irish 1000 Guineas by no less than six lengths at the Curragh subsequently, clearly making quite extraordinary improvement from her maiden success.
Miss Dela, however, wasn't seen again, obviously she had problems, until making her reappearance at the Curragh over two weeks ago.
It was a most encouraging return, taking a creditable fourth behind some smart three-year-old's, Athenian Way, Regalline and Peeping Fawn, with another useful sort, Many Colours, behind in fifth.
Regalline, Peeping Fawn and Many Colours all ran well at Gowran Park on Sunday and Miss Dela's form now reads particularly good, in the context of this opposition.
For A Song, who shouldn't be too inconvenienced by the surface, can provide the answer to the Treacys' Pharmacies Beginners Chase.
Relatively experienced, he has two decent efforts over fences in his locker, taking second to Mercuric at Thurles and Priests Leap at Limerick.
Ruby Walsh partners For A Song and his booking for English-import Forthright, in the Roundfort Stores Hurdle, looks significant.
Now in the care of Mark Loughnane, Forthright was mildly disappointing at Aintree on Grand National day when only eighth, he went off favourite, behind Kings Quay in a competitive handicap.
That form was boosted, though, when Oslot, a place and two and a half lengths adrift of Forthright, scored at Sandown last Saturday.
Ballydungamanor, teaming up with Nina Carberry for the first time and with two reasonable efforts under his belt, is the choice in the Bumper.
