Thanks for your comment Amarillion, I often do that, to put in the second verse the original artist of the song as a reminder (especially when they're on the same key), but on this one, I thought the pairing was so unexpected and worked so well that I wanted Oasis to sing on the full song (with ABBA sometimes on backing vocals only), as they are only 2 choruses on this song
Great mashup, although I would have allowed the second drop to be a proper 'Dancing Queen' chorus as the song was seemingly building up to that huge reveal.
